manage old dockerhub images

How do you keep track and solve the problem of old dockerhub images ? my own images are updated and rebuilt every day. no problems here. But i just noticed that i am using old images from dockerhub ( one of them is 5 years old :) ).

i was considering valid options arround this :

1. create a dockerfile using "FROM dockerhub/image" and adding apt-get update & upgrade. set the cicd and then using this image instead of dockerhub's
2. find a fork and use it
3. find a concurent project and migrate my config and use it
4. develop it my way

Any recommended automations ?

Recently moved into a DevOps role and I’m relatively new to the DevOps realm.

Though, I have a decent understanding on how the tools work together and end goals.

With that said, I was curious to know if anyone implemented any automations in their day to day work that they would recommend ?

Deploying to multiple environments using Gitlab-Terraform

So I am currently making the transition from cloud formation to gitlab-terraform and I'm trying to wrap my head around trunk based deployment. We've done branch-per-environment in the past and have seen the pitfalls of that, so I am trying to see if this is a better solution.

A few hurdles we have is that we have three environments: Dev, Test, and Prod. And we have two gitlab servers. One responsible for deploying to Dev and the other is responsible for deploying to Test and Prod. It's a requirement for security purposes that I don't really want to get into, but syncing code between servers isn't the issue I am having.

I am confused on using one branch to deploy to multiple environments. I currently have the standard gitlab ci-yml working and we also pull in auto.tfvars file during the setup phase to control environment specific values. On the success of a development merge, we sync the code to the 2nd gitlab server, so that it can be used in the test / prod environment.

I guess my question is how am I supposed to handle deploying to test and prod with a single MR? I could definitely do it sequentially, where I run through my stages [setup, validate, plan, deploy\] again and swap out the environment variable so that the correct tfvars comes. But that seems clunky / wrong?

What is the cleanest way of doing this? Am I supposed to have a pipeline that goes sequentially? Or is there a slicker way of doing test / prod in parallel where I have two plans at the same time representing both environments that can be manually deployed? I feel like I am missing something here and haven't really been able to find a full solution yet.

I want to be able to deploy apps as quickly as possible to on-prem k8s. I was looking at Jenkins-x with their jx create command, looks pretty powerful, but it looks complicated to setup. Any easier alternatives?

How to manage and release features to different customers in both SaaS and self-hosted environments

Many organisations struggle with how to maintain a single repository and master branch to continuously deliver their software to their customers who require different features.

Some customers use online SaaS services, but some customers need to deploy in a private and self-hosted environment. You're struggling with how to keep the same released version.

If a new feature is only built for one particular customer at the beginning, you're struggling with how to canary ship a new feature to that particular customer and keep the same code for all the other customers.

You also struggle with how to respond quickly to customer requirements without involving too many engineers. If a customer success team can do that without engineers, that's perfect.

How to mitigate the situation?

Feature Flags Management Service is the must-have technology to solve these scenarios. Feature Flags is a modern engineering technology that decouples code deployments from feature releases, giving you control over who sees each feature and when they see it.

Feature Flags can be categorized into four pillars (Release Flag, Experimentation Flag, Operational Flag, and Permission Flag) in its lifecycle through development to customer success.

Operational flags and permission flags can be used to manage entitlements in software, which refers to controlling what features or functionality a user has access to based on their subscription or payment plan.

Release flags and experiment flags can help you to deliver a feature to a specific customer with minimal risk. It allows teams to test new features in production and progressively (percentage rollout) release the new feature to targeted customers to reduce the "blast radius".


I wrote an article of how to use feature flags to manage and release features to different customers in both SaaS and self-hosted environments. I hope this can help and get feedbacks.

📢 DEPRECATION ALERT: Mar 20 traffic from the old Kubernetes registry k8s.gcr.io will be redirected to registry.k8s.io

📢ICYMI this Monday, Mar 20, traffic from the older k8s.gcr.io Kubernetes registry will be redirected to registry.k8s.io


If you run in a restricted environment and apply strict domain name or IP address access policies limited to k8s.gcr.io, the image pulls will not function after k8s.gcr.io starts redirecting to the new registry.


How can you know if you're affected? it only takes a single line kubectl command to find images from the old registry! (see on the below post)


The deprecated k8s.gcr.io registry will be phased out at some point. Please update your manifests as soon as possible to point to registry.k8s.io.


This is actually good news, as the new Kubernetes community image registry registry.k8s.io will save major egress traffic costs for users not running on Google cloud ☁️

Question About Linking Repository To CI/CD

So I have a user account on the company Gitlab server.

When I want to link a repository to the company CI/CD tool by adding a custom private SSH key to CI/CD, am I adding the private SSH key that is linked to the public key of my own user account in Gitlab?

Am I correct in assuming this can't be right as everytime the CI/CD tool uses that REPO, it will have to pull the repo from my own Gitlab user account?

If this is the incorrect way to do it, what is the correct way to do it?

Test data for performance testing

There's some overlap here with data engineering and QA, but I'm more looking for information about how this problem is addressed in other companies and the role of devops/platform in it.

We badly need performance tests. Our service is used by hundreds of thousands of people all around the world. It has fallen over more times than I care to admit and I'm still a bit gobsmacked that we don't have any.

A sticking point we have is that the data in our non-production env where we would do these tests does not have anything like the same volume of production. We have many production RDS databases running on our platform. Our dot on the horizon is for the data from all these DBs to be ingested into a data warehouse where it can then be forwarded to multiple different endpoints. One of those would be the DBs on a non-production environment with a masking layer in between to scramble any sensitive columns. I'm glad we're agreed on the plan, but it feels quite ambitious and the data team who are building this aren't going to have it ready for a long time.

In the meantime, we need something a bit more straightforward. My first thought is to generate dummy data with a similar volume as production. It wouldn't be as good as data sourced from production but it would still allow us to get some value out of performance tests. Creating it looks to me like something that would be driven by developers and QAs, but I have little experience of doing it myself so I'm not sure how feasible it really is.

Can anyone share anything about how they've seen this problem tackled? Also setting up performance tests seems to be a task that involves different expertise working together (dev, platform, QA, data etc), so I'm curious about the different responsibilities that each role typically takes on. Thanks.

Stuck on this fluentd parsing issue

tl;dr: I want to pull 2 fields from a log file that is a mix of json and log headers.

I'm a bit new to doing anything with fluentd that's doing anything other than fancy regex. Now, I'm trying to parse some logs that are partially JSON, then extract a few field and forward them on to their destination (stdout for now). Here's a log sample:


2023-03-09 00:00:00,029 (threadpool-12345) INFO [HiIAmALog] {statusMessage":"uh oh","status":"FAIL","totalTime":5,"code":34}

And here's my source:

<source>
@type tail
@id tail_log
tag log
path /tmp/log
pos_file /tmp/log.pos
time_format %Y-%m-%dT%H:%M:%S.%L%Z
keep_time_key false
read_from_head true
open_on_every_update true
<parse>
@type none
</parse>
</source>



I'm chopping off everything below the JSON string using a filter and a ruby gsub:

<filter log>
@type record_transformer
enable_ruby
<record>
message ${record["message"].gsub(/20.*HiIAmALog\] /,'')}
</record>
</filter>


This gives me a nice, clean JSON string as output:

{message":"uh oh","status":"FAIL","totalTime":5,"code":34}


Next, I'm trying a filter like this to get just statusMessage and code:

<filter log>
<record>
statusMessage ${record["statusMessage"]}
code ${record["message"]["code"]}
</record>
type record_transformer
enable_ruby
</filter>

I know at this point this is just a string, not a JSON object, so I can't actually parse the fields. I've tried using ruby to_json method to transform it, but it's not working. Does anyone have any suggestions? I've been banging my head on this for too long. Thanks in advance for any help you can give.

An adventure with SLOs, generic Prometheus alerting rules, and complex PromQL queries

I'm working on a library called Autometrics that makes it easy to add metrics to a code base and recently worked on support for SLOs/alerts. We ended up with a solution that enables us to have a single set of Prometheus recording/alerting rules that will work for any autometrics-instrumented project and the libraries use some fun label tricks to enable specific rules.

I wrote up a blog post about this experience here in case others are interested: https://fiberplane.com/blog/an-adventure-with-slos-generic-prometheus-alerting-rules-and-complex-promql-queries
