Managing a manual release process

We have a slightly manual release process. Pipelines get everything ready, and the last step requires a human to click 'go' on the end, having sought approval.

Approval is generally required from two people, one who is aware of all the releases going on ('air traffic control') and another who is technically aware of what's in the release (technical approval).

Currently, we do this with a slack workflow, which is predictably poor; it's easy for requests to get missed or buried in a slew of change requests. It's also easy for the wrong people to click 'approve'.

It feels like we're not the only company doing this; what are the good tools/processes you're using around a business need to have this sort of approval in the way of a release? I've been having a look around and not found anything, which makes me think I'm using the wrong words or something.

Thanks!

Devops and Game Servers?

With the launch of Diablo recently (a video game for those that might not know), it had me thinking. I’m sure their infra team had to greatly prepare for the influx of players. Assuming they have created an environment that can scale up and use more resources if needed.

I am genuinely curious from the Devops perspective how this was achieved, to have such a stable launch. So many players and minimal downtime. Not necessarily each specific detail, but the philosophy, tools used, things like that. Are the servers run using cloud providers, or their own on prem? How can I learn more about this? Or if anyone has insight / resources I could read on. Thanks!

Chef Berks vs Chef-Client distinction

So I was having some issues with some cookbooks due to depencies and am relatively new to chef.

In a meeting discussing these issues, there was a distinction made between Berks resolution and Chef's resolution(or more specifically chef-client) for dependencies being two different things, which was what was causing the dependency issue.

When they said Chef, I recall them stated meaning Chef-client, however I am still not sure what exactly Berks is, or rather the distinction made since.

Isn't Berks part of Chef anyway? I am a bit confused by the distinction.

Im a recent graduate from Industrial engineering, all my studies had very minimum coding usage and recently i decided to get into Devops as the jobs i get to do with my degree in Industrial engineering pays way more less. Can any one please tell me the blue print on how to learn devops and whats the future for devops.

Im kind of debating between Devops/Sap development/ Data Engineer roles.

Can some one please tell me me choosing which field has a better future.

Sematext Monitoring Tool

Hello All

My current company is using a mix of New Relic and Splunk for log management, infrastructure monitoring, and apm. However, we are trying to switch from New Relic due to its cost. We are currently evaluating Splunk Observability but finding it lacks some infrastructure and apm metrics we want to see and the interface is not intuitive.

While doing some research on other solutions, I came across Sematext. It looks promising and I was wondering if anyone has used it before? If so how was it and is it worth trying out?

Thanks

Prometheus: scrape pods from just a particular node?

Is anybody familiar with a way on how to scrape Kubernetes pods from just a particular node?

I’m trying to figure out have to have multiple Prometheus scrapers in a single cluster without scraping the same endpoints and duplicating metrics. My thoughts are to use a daemonset and have some pod scraping affinity.

Thoughts on CI/CD workflow for small team creating an online web application

I wanted to improve our CI/CD pipeline since right now we are a small team working a web application with a frontend and backend and we are doing everything pretty much manually.

The idea I have so far is have 2 persistent branches, main and prod.

* The main branch contains everything that we want to deploy next
* When we want to create a new feature we branch off main and once the feature is done and ready to be deployed is merged back to main using a PR request.
* Anytime something in the main branch changes our CI/CD pipeline (AWS CodePipeline) will build the docker image, run tests and deploy it to our staging server.
* After checking that everything works as expected in staging we can merge into production which does pretty much the same but deploys into production server/servers instead.
* If we have a bug in production we can create a hotfix branch where we fix the bug, this gets merged back into main to test it in the staging server and if everything works well the hotfix gets also merged into production (not sure about this part here since the fix will be tested in staging next to a lot of unreleased features, in this case staging is not a 1 to 1 with production)

If we want to avoid having the staging pipeline being triggered all the time (for example we are adding a lot of features and we dont need to see them yet in staging) we can implement a manual check in our pipeline that we have to click on to build and deploy into staging.

What do you think, does this sound like a good way of doing this?


In a different post someone suggested only having 1 main branch and "promoting" the stage build into production. But i have no idea how to do that.
Also, we have different AWS accounts for stage and prod, so not sure if that will even make it more difficult.

API Mock or testing with output to Prometheus

Hi, I am looking for API Mock or API testing, to write some small testing, login, some basic function or GET Requests in index and save the result to prometheus maybe.

1 RabbitMQ, 2 ways of access

I would like to deploy one single instance of RabbitMQ on standard AMQP port in a Kubernetes cluster.

The special request is that it should only be needed user+password for internal Kubernetes requests, and it should use 2FA with user+password AND mTLS for public requests from outside Kubernetes.

Is this in any way possible? How could this be tackled? As far as I have read, you are only able to configure mTLS for all or for none...

DevOps Engineer Roles and Responsibilities

A **DevOps engineer** works with both the development and operations teams to create and implement software systems. Therefore, they need to collaborate with software developers, quality assurance professionals, and other IT staff. A DevOps engineer’s main roles and responsibilities include:

· Write documentation for the server-side features.

· Develop, install, test, configure, and maintain IT solutions.

· Communicate operational requirements and development forecasts with everyone in the team.

· Develop plans and processes for improvement and expansion of the current technologies being used.

· Deploy updates automatically into the production environment using configuration management software.

· Perform routine application maintenance and troubleshooting measure to ensure the production environment runs smoothly.

· Perform gap analysis to identify performance enhancements, identify alternative solutions, and assist with modifications.

Programming Language and Linux Fundamentals

DevOps uses programming languages for developing and automating software. To become a DevOps engineer, there are several programming languages you need to learn in addition to specific DevOps tools.

The three most common languages used with the DevOps tools are Ruby, Python, and JavaScript. It's advisable to learn at least one of these programming languages to work with the DevOps tools.

It's also essential for a DevOps Engineer to know the fundamentals of the **Linux Command** Line Interface (CLI). The mandatory Linux skills that a DevOps engineer should have include:

· Linux shell - bash or ksh

· Linux commands - find, grep, awk, sed

· Networking commands - nslookup and netstat

### Source Code Management

The next milestone for a DevOps engineer is to learn source code management. This is essential for keeping your projects organized, regardless of the number of code sets you have. Learn at least one of these standard source code management tools:

· Git

· CVS

· Mercurial

Aside from programming more on the job, which of these books are relevant enough to DevOps to be worth picking up? These happen to be the most recommended Software Engineering books:

Clean Code
Head First Design Patterns
Pragmatic Programmer
Refactoring
Designing Data Intensive Applications

 


And regarding DevOps books, I'm having a hard time deciding which ones to read and which to skip?:

Phoenix Project
Devops Handbook
Accelerate
Unicorn project
Google's SRE book and/or workbook
