How to document your CI/CD chain?

Hello, I have a simple question, I have Three environments, with a Kubernetes cluster and bench of AWS resource for each env, deployed using Terraform, the CI/CD chain has Many Pipelines, we also use Jfrog Artifactory and Github, I need to document the work, and don't know how to summarize and document all this infrastructure and ci/cd chain, I have searched online, but I haven't found anything useful.

So my question is how do you guys document your CI/CD work for future colleague? and how would you structure it?
Thanks in the advance

From Docker to OCI: What is a container?

Let's review the basics: What are containers suitable for, and how do they work? I get a lot of questions about containers and Docker, so I wrote [an article perfect for anyone new to DevOps](https://www.padok.fr/en/blog/container-docker-oci). Check it out and tell me if it seems more accessible to you.

Jenkins Reporting to Bitbucket

Currently I have an automated Bitbucket webhook process that triggers a Jenkins suite of unit tests.

I would like to have my Jenkins job send back to Bitbucket if the job build passed or failed.

Suggestions?

Exams and DevOps Certifications

Recently i was fired from a DevOps position and received a good amount from unemployed insurance, since i have the money and the free time, i am thinking in investing both in getting some training in the field.

​

Is it worth it ? I'm quite competent with many of the tools already, i'm just looking for a better foundation to it and a quickier reinsertion in the field with more experience.

if it is

​

Wich certifications would you pursuit or suggest ? I was thinking in LPI DevOps Tools Engineer and CKA, but besides of that im not quite sure, should i go for OS certifications too , like RHCSA ?

​

​

also i would like to thank this sub that was very helpfull to me since 2015 and certanly played a big part in me transitioning from a sysadmin job to a devops.

Elixir app network performance testing

I'm tasked with testing/benchmarking a client-facing app that accepts http api requests. The app stack is composed with Elixir / Phoenix / Ranch and Cowboy 2 as the web server. Hosted on an ec2linux box, connected to a RDS DB and running behind an elastic load balancer, network type.

I'd say I have an OK amount of basic knowledge about networking in general, the TCP/IP stack and how things tie together to 'just work'.

What I'm struggling with is performance optimization which could be anything from latency and bandwidth, sufficient provisioned resources, kernel configuration etc. (these are just some I can think of)

How do I identify potential bottlenecks when, lets say request start to time out? If the Cowboy worker pool gets increased, when would I know that the provisioned ec2 resources are not sufficient enough?

Do you apply some sort of methodology to performance-optimize a web app? Or does this come down to purely getting a feel for it and experience?

I guess what I'm lacking is knowledge of how these things are dependent of each other and what effect it does when adjusting one parameter to the rest.

The cloud - Trust yet Verify EVERYTHING!

No Cloud migration is ever without pain. Moving a business application from a datacenter to a cloud will always create concerns around security, privacy, availability and performance. While each of these can be mitigated, there is always an element of "trust" that has to be believed. Your basically giving some control over to the cloud and hoping they (whoever they actually are) do exactly what they say they will do.

The benefits in terms of cost and scale can be wonderful, but it doesn't help a CIO sleep better knowing that youve given up some level of control.

It can be very hard to trust , yet verify without adding layer upon layer of monitoring that didn't exist previously.

Infra.app - Desktop app for managing Kubernetes

I saw this Mac app from the r/Kubernetes thread for managing Kubernetes clusters. The experience is great so far.

On-prem Jenkins over k8s VMs storage

How would you tackle the persistent storage part?
Cluster will be built upon 3 worker nodes.

We have a cifs storage mount in the office, and from my reading, there is a cifs driver on GitHub(as currently no official cifs drivers by kubernetes) but repo not really alive.. https://github.com/fstab/cifs

Thinking to bring up a VM running NFS server, and connect the cluster nodes, but it is not so good approach as single point of failure when this VM will crash.(and it will ..)

Any fruitful thoughts?

GitHub CLI (Beta) for more efficient PR's

Check out my video on the new GitHub CLI tool which is currently in Beta!

It allows you to create, get the status of, and view in the browser all Issues and Pull Requests for a repo straight from the CLI!

Great tool!

Ideally, enterprises should not have a designated DevOps team, according to Jennifer Davis, co-author of Effective DevOps and senior software engineer at Chef Software

Thoughts? We have lots of different app teams at my company. I wouldn't expect these developers to maintain cloudformation scripts, ansible playbooks, develop codebuild/codedeploy scripts, configure pipelines... If the Devops team can interface among these disparate entities and automate their build procedures--what's wrong with that?
