We'll cover everything from weekly production updates to handling tricky firewall rules, all while maintaining a friendly, conversational tone. So, buckle up, grab your favorite beverage, and let's explore how we make Packit Service shine!
The Weekly Production Deployment Ritual: Ensuring Packit Runs Smoothly
Every Monday, the heartbeat of Packit Service development aligns with our weekly production deployment ritual. We've set a consistent time, usually kicking off around 1 PM, aiming to wrap things up by 3 PM. This structured approach helps us minimize disruptions and provides predictability for both our team and, most importantly, our users. Before we even think about hitting the deploy button, there are a few critical steps we religiously follow to ensure the integrity and stability of the Packit Service environment. This meticulous preparation is key to preventing unforeseen issues and ensuring a seamless transition of new features and fixes into production. We’re talking about a comprehensive check-up that covers everything from team consensus to the health of our staging environments. This isn't just a checklist; it's a commitment to delivering top-notch service to everyone relying on Packit Service for their development workflows. It ensures that the latest Packit Service updates are rolled out smoothly and effectively, enhancing user experience and overall system performance. We take pride in this methodical approach, as it reflects our dedication to maintaining a robust and reliable Packit Service for the community.
Initial Checks: Before You Hit Deploy
Before we embark on any Packit Service deployment, our first and most crucial step is a comprehensive round of initial checks. This isn't just a formality, guys; it's the bedrock of a successful and stable deployment for Packit Service. First off, we always — and I mean always — check in with the team, either during our stand-up or in the chat. We need a collective thumbs-up, a shared understanding that deploying new changes from our main branches is safe and won't introduce any unexpected hiccups into Packit Service. This collaborative approach helps us catch potential issues early and ensures everyone is on the same page regarding the readiness of the latest Packit Service features.
Following the team sync, our attention immediately shifts to the current state of our staging deployment. This environment is our sandbox, our proving ground before anything goes live in Packit Service production. We meticulously check the OpenShift cluster to ensure all pods are healthy, services are running as expected, and there are no lingering errors. A quick glance at Sentry is non-negotiable; we're looking for any new errors or increased error rates that might indicate instability. Sentry gives us real-time insights into the health of Packit Service, highlighting potential issues that could impact users. Lastly, our dashboard provides a high-level overview of Packit Service's operational status, giving us a visual confirmation that everything is green and looking good. These checks are absolutely vital because they act as our early warning system, allowing us to identify and address problems in a low-stakes environment before they ever reach our users on the production Packit Service. It’s all about being proactive, ensuring the quality and reliability that our users have come to expect from Packit Service.
Communicating with Our Awesome Users
Communicating proactively with our users is a cornerstone of our Packit Service deployment strategy. You see, guys, transparency and timely updates aren't just good manners; they're essential for maintaining trust and ensuring a smooth experience for everyone who relies on Packit Service. That's why, once we've given the green light to proceed with the deployment, our next step is to update the channel topics on both our Matrix and Slack chats. This isn't just a quick text change; it's a vital notification system designed to inform users that we're about to redeploy Packit Service. We want to make sure no one is caught off guard by a temporary interruption in service or a slight delay in response times. The goal is to set expectations, offering guidance on what to do if Packit Service seems unresponsive during the brief update window.
We craft messages that are clear, concise, and helpful, like: "We are redeploying the Packit Service production. If Packit does not react to your actions for a long time (30 minutes) try retriggering it with /packit build, /packit test, /packit propose-downstream, /packit pull-from-upstream, /packit koji-build, /packit create-update." or a more direct "⚠️ Production redeployment in progress. ⚠️". These messages provide immediate value, empowering users with solutions if they encounter any transient issues. This step isn't just about informing; it's about empowering our Packit Service community, letting them know we're actively working to improve the service and that we've thought ahead about potential temporary disruptions. This commitment to clear communication is a huge part of what makes Packit Service not just functional, but also a user-friendly and reliable platform.
The Core Deployment Process: Moving main to stable
Alright, folks, this is where the magic happens – the core of our Packit Service deployment! Once all checks are cleared and users are notified, we proceed with the critical task of moving content from our main branches to the stable branches. This action essentially promotes all the fantastic new features, bug fixes, and improvements developed over the past week into the production-ready state for Packit Service. It’s a moment of truth, a culmination of all the hard work from the team, and it directly translates into an enhanced user experience with Packit Service.
However, a word of caution here: image builds can be a bit of a time sink. We’ve recently added support for additional architectures, especially aarch64 emulation, which has extended the build time to around 40 minutes. This is a necessary investment for broader compatibility and reach for Packit Service, but it means patience is definitely a virtue during this phase. After the stable branches are updated, we meticulously check the Actions tab on our respective GitHub repositories to ensure that the images from these stable branches are successfully built and pushed to Quay.io. Quay.io is our image registry, and verifying these pushes is absolutely crucial for the Packit Service to pick up the latest versions. While we're in Quay.io, we also have a handy reminder: roughly once a month, we perform a vital cleanup operation. We sort repositories by "last modified" and remove older, unnecessary images that gobble up valuable space. This not only keeps our registry tidy but also optimizes storage costs and ensures that Packit Service can always access the most current and relevant images efficiently. This routine maintenance is a small but significant part of keeping Packit Service lean and mean.
Beyond the Code: Kubernetes, OpenShift, and Vault Updates
Sometimes, a Packit Service deployment isn't just about new code. The infrastructure itself might need an update to keep pace with the evolving demands and features of Packit Service. This means we need to pay close attention to any changes in our Kubernetes/OpenShift objects or modifications within Vault. These infrastructural tweaks, such as new service definitions, configuration changes, or updated secrets, are just as vital as the code itself for the seamless operation of Packit Service. If there have been any such changes in the deployment repository or in Vault that haven't yet been applied to production, it's our responsibility to make sure they are. We usually check with the author of the change to confirm if it has been applied or if it’s pending.
This is where the DEPLOYMENT=prod make deploy command comes into play. Running this ensures that our production environment, where Packit Service lives, is fully synchronized with the latest infrastructure configurations. It's a critical step because out-of-sync configurations can lead to all sorts of headaches, from services failing to start to incorrect behavior. By proactively applying these changes, we ensure that Packit Service not only receives its new features but also operates within an environment that's perfectly tailored and secured for its latest iteration. This diligent attention to both code and infrastructure is what makes Packit Service incredibly robust and reliable, providing a stable platform for all our users.
Post-Deployment Validation: Verifying Packit Service Health
Alright, guys, you've pushed the code, updated the infrastructure, and patiently waited for the images to build and deploy. But our job isn't done yet! The minutes immediately following a Packit Service deployment are critically important for validation. We need to be absolutely sure that the new images are not only imported into Quay.io but also successfully pulled into our production deployment, and that Packit Service is running optimally. This post-deployment verification phase is non-negotiable; it's our final checkpoint to guarantee that everything is working as intended and that our users will experience a seamless and improved Packit Service.
Our validation process is multi-faceted. First, we head straight back to the OpenShift Cluster console for our production environment. We're looking for green lights across the board – all pods should be running, services healthy, and no unexpected restarts. Next, Sentry becomes our best friend again. We meticulously check for any new errors or spikes in existing issues within the last 24 hours (or even shorter, for immediate feedback). Any anomalies here are red flags that require immediate investigation. Finally, we visit the production dashboard to confirm that Packit Service is fully operational and displaying the expected metrics. If all these checks pass with flying colors, we then revert the topic change in our communication channels, letting users know that the Packit Service deployment is complete and normal operations have resumed. This thorough validation ensures that every Packit Service update enhances rather than hinders the user experience, solidifying our commitment to reliability and performance.
Spreading the Word: Packit Blog Posts and Social Media
After all that hard work bringing the latest and greatest to Packit Service, it’s time to share the news! Creating a compelling blog post is not just an optional extra; it's a crucial part of our Packit Service deployment cycle. This is how we connect with our community, highlight the value we're delivering, and keep everyone informed about the exciting progress of Packit Service. Our blog posts, typically titled "Packit [in] $MONTH $YEAR", serve as comprehensive release notes, detailing everything that's changed in Packit and Packit Service's main branches since the last stable update.
We leverage tools like scripts/move_stable.py github-query to easily gather links to all relevant PRs marked for release notes, providing a fantastic starting point. This helps us ensure we don't miss any important updates for Packit Service. But it's not just about listing changes; it's about telling a story. The blog post needs to be written for a general audience, making it easy to understand even for those with minimal technical background. We focus on new features, notable bug fixes, documentation updates, and UX improvements that directly benefit the user. We steer clear of internal jargon, refactoring details, or CI changes, because, let’s be honest, our users care about what Packit Service can do for them. We aim for clarity and relatability, using examples that make the changes tangible and exciting. For instance, instead of saying, "Packit's behavior in dealing with spec files was improved," we might say, "Packit can now find a spec file inside a bottle of rum which is very handy when you're thirsty." This approach makes Packit Service updates engaging and accessible. Once the blog post is polished and published, we also create an optional, concise Mastodon post, mentioning the top news. Remember, Mastodon has a 500-character limit, so it often requires a shorter, punchier version or splitting content into multiple posts throughout the week to maximize exposure for Packit Service.
Handling Access Issues: Requesting Firewall Rules for Packit Service
Sometimes, even with the most robust Packit Service deployment and meticulous maintenance, we encounter external obstacles. A common one is when Packit Service cannot access a specific external domain. This typically happens when Packit Service needs to download sources for downstream release automation, and a new domain has been introduced that isn't yet whitelisted. When users report such access issues, it's a critical priority for us, as it directly impacts Packit Service's ability to perform its core functions.
The first step in resolving this for Packit Service is to verify the inaccessibility. We use simple commands like curl -I --max-time 5 <domain> within both our prod and preprod OpenShift clusters to confirm that the domain is indeed unreachable. This verification is essential to rule out any other potential network or configuration issues specific to Packit Service itself. Once we've confirmed it's a firewall issue, we proceed to formally request the necessary firewall rules. This process is thoroughly documented on packit.dev/deployment/specifics/clusters#firewall, ensuring we follow the correct procedure and provide all required information to the network team. We then meticulously track the progress of this request, often by creating an issue that allows us to monitor its status and communicate updates to the affected users. This proactive and documented approach ensures that Packit Service maintains its connectivity and can continue to support our users’ development workflows without interruption.
Essential General Instructions for Packit Service Gurus
Beyond the weekly rhythm of Packit Service deployments, there are several general instructions that every Packit Service Guru should have at their fingertips. These guidelines cover everything from how we communicate with our users during a deployment to the intricate details of how to manage our stable branches and troubleshoot unexpected issues. Adhering to these instructions ensures consistency, minimizes downtime, and ultimately provides a more reliable and predictable experience for everyone interacting with Packit Service. They represent the collective wisdom of the team, distilled into actionable advice to handle various scenarios that might arise during the lifecycle of Packit Service. Mastering these details is crucial for anyone involved in the maintenance and operation of our platform.
Mastering User Notifications
Guys, let's talk about user notifications again, because they are that important for Packit Service operations. Notifying users about upcoming or ongoing Packit Service redeployments isn't just a suggestion; it's a fundamental responsibility. We use both Matrix and Slack channels, and the primary method is by adjusting the channel topic. This subtle yet effective approach ensures that the information is persistent and easily visible to anyone checking the chat. The goal is to set clear expectations and provide guidance, reducing anxiety and confusion if Packit Service momentarily seems unresponsive. Example messages are crafted to be informative and proactive, offering solutions like: "We are redeploying the Packit Service production. If Packit does not react to your actions for a long time (30 minutes) try retriggering it with /packit build, /packit test, /packit propose-downstream, /packit pull-from-upstream, /packit koji-build, /packit create-update." or a concise "⚠️ Production redeployment in progress. ⚠️". If changing the topic doesn't automatically generate a message, we make sure to send one manually. This proactive communication is a testament to our commitment to a user-centric Packit Service, ensuring our community is always in the loop and feels supported during critical maintenance windows. It’s a key part of our agile operations.
The stable Branch Dance: Keeping Packit Sync'd
Managing the stable branches is a core part of our Packit Service deployment routine. To do this effectively, you need a clone of the deployment repository, and critically, your SSH keys must be correctly associated with your GitHub account. This setup is essential for the move-stable script to function properly. When it’s time to move the main branch content to stable, we simply run make move-stable. This script automates the process, ensuring that the stable branch for each relevant Packit Service component reflects the latest, production-ready code. However, sometimes things don't go perfectly, and pushing the stable branch might fail. This could happen, for instance, if some changes had to be cherry-picked directly into production, causing a divergence in history.
In such scenarios, where the stable branch is out of sync or the push fails, it's perfectly acceptable, and often necessary, to force-push the current state of main as stable. This action effectively overwrites the stable branch with the main branch's history, bringing everything back into alignment and ensuring a consistent foundation for Packit Service production. While force-pushing should always be done with caution, in this specific context, it's a clean way to sync up the history and ensure that our production environment is always running the intended latest stable version of Packit Service. It’s a vital part of maintaining a consistent and reliable Packit Service production environment.
Deep Dive into Redeployment Specifics
Understanding the intricacies of Packit Service redeployment is crucial for any Service Guru. Our system is designed for efficiency: newer images are automatically imported from Quay.io, and pods are recreated from them in the same continuous deployment fashion as our staging environment. This automation is a significant part of what makes Packit Service so robust. However, sometimes things don't go as planned. For instance, pods can get stuck in a terminating status for an extended period. If you encounter this, don't panic! A quick oc delete pod --force ‹pod-name› will manually kill the stubborn pod and allow OpenShift to spin up a fresh one. Another common issue is Error: ImagePullBackOff, which indicates that a pod can't pull its image from Quay.io. If this happens, you can manually import the images using DEPLOYMENT=prod make import-images to give Packit Service a nudge.
Furthermore, if a previous Packit Service deployment has been reverted – perhaps due to a significant regression or critical failures – it's imperative to consult with the team and refer to our documentation on continuous-deployment.md#reverting-to-older-deploymentrevisionimage for the correct next steps. Reverting a deployment is a serious action, usually taken if all jobs fail or there's a severe functionality regression, signifying an urgent need to restore Packit Service stability. When in doubt, checking the latest deployed versions via https://prod.packit.dev/api/system or https://stg.packit.dev/api/system can provide immediate clarity on the active Packit Service versions. These detailed troubleshooting steps and fallback procedures are vital for maintaining the high availability and reliability that users expect from Packit Service, demonstrating our commitment to keeping the platform robust and resilient.

It’s not just about listing changes; it’s about connecting with our community and showcasing the incredible work that goes into Packit Service. Our blog posts are meant to be read by the general public, so the golden rule is: make it easy to read for everyone. This means ditching the internal jargon and technical minutiae, and instead, focusing on what truly matters to our users. We strive for content that highlights new features, notable bug fixes, documentation updates, and user experience improvements – anything that directly enhances how someone interacts with and benefits from Packit Service.
Conversely, we consciously avoid talking about internal things like most ogr or specfile changes, refactoring efforts, or CI adjustments. While these are vital for us internally, they don't typically offer immediate value or clarity to a broad audience using Packit Service. The key is to write in a way that allows people with even a little knowledge of the project to grasp the essence of the change. For example, instead of a dry, "Packit's behavior in dealing with spec files was improved," we aim for something more engaging and relatable, like, "Packit can now find a spec file inside a bottle of rum which is very handy when you're thirsty." This makes the Packit Service updates more digestible and even fun! When it comes to sharing on our Mastodon account, be mindful of the 500-character limit. Often, this means creating a shorter, punchier version or strategically splitting content into multiple posts throughout the week to ensure that all the exciting Packit Service news gets the attention it deserves. It’s all about maximizing reach and impact for Packit Service.
