devstream VS Ansible

About nine months ago, DevStream was first publicly released. Since then, it has evolved a lot. If this is the first time you have come across DevStream, maybe read this blog for a quick overview.

DevStream Source Code Repository

Hacktoberfest by Digital ocean always excites the Open source community at large. In this 2022 edition, Apache DevLake and CNCF DevStream projects are participating in Hacktoberfest. Our goal is to enable contributors to learn and grow together with the community.

See the full changelog here.

This is Tiexin Guo, DevStream PMC Chair (an open-source DevOps project with an enthusiastic community.)

@aeinrw made their first contribution in https://github.com/devstream-io/devstream/pull/456

I’ve been working as a DevOps engineer since 2016, and as of today in 2022, I'm still working on it (as the PMC of DevStream). In 2021, I was lucky enough to join AWS as a Senior (L6) DevOps (already left, though). But this article doesn’t represent AWS’s view; nor does it represent my current corporate view. It’s my personal opinion, which I learned and formulated over the years of hands-on experience in projects.

If you are intrigued by the simplicity of "DevOps toolchain as code", don't hesitate to check out DevStream here.

They support for-if from python, too: https://jinja.palletsprojects.com/en/3.1.x/templates/#loop-f... but I haven't tried the "recursive" keyword to know if ansible supports that. I say "ansible supports that" because they don't just drop jinja2 into ansible and call it a draw, they have a bunch of custom execution integrations: https://github.com/ansible/ansible/blob/v2.16.3/lib/ansible/...

To manage a VM, you can use something as simple as just manual actions over SSH, or can use tools like Ansible, Hashicorp's Packer and Terraform or other automations. For an app where there is minimal load and security/reliability concern, VMs are still a great option that provide a lot of value for the buck

In this article's context, it is simply a tool that provides a declarative way to automate your machine/OS to configure the development machine as you want (install package, modify the configuration, etc). Examples of these tools are Ansible, Puppet, etc.

Now we're getting more tangential, but for years, Ansible releases were named for Van Halen songs (see old Changelog here: https://github.com/ansible/ansible/blob/v1.8.4/CHANGELOG.md)

In the lab to follow, we'll quickly provision a 3-node kubeadm cluster (1 master, 2 workers) on the cloud provider of your choice using an automation stack comprised of OpenTofu and Ansible, then deploy Rook Ceph using the official Helm charts and confirm that we are now able to successfully create CSI volume snapshots from PVCs by reusing the MinIO example from our last article.

Ansible-Core ↗

The lookup works fine when parsed as say a msg and braced in "{{ }}" but we're told not to use jinja delimiters in when statements (no idea on the whys to that to be honest) - The issue lies around the first ": " and yaml sees that everything preceding this being a mapping... I have tried all manner of fixes described in YAML syntax error when string contains a colon + space · Issue #2769 · ansible/ansible (github.com) but no dice... the error is a variety of 'The error was: template error while templating string' type errors depending on what attempted fix I'm applying..

IBM -> RedHat -> Ansible (https://docs.ansible.com/platform.html)

I think the new ansible docs are opaque, and the new "everything is an ansible collection" scheme makes troubleshooting any issues reported by users hundreds of times harder than "the old days"

I keep this (https://github.com/ansible-community/ansible-build-data/blob...) bookmarked because it's the only way to match up what "ansible 8.1.0" (https://pypi.org/project/ansible/8.1.0/) even means since it for damn sure not any of this: https://github.com/ansible/ansible/releases (they used to have a 'release' pinned on that releases tab saying "these are not the droids you are looking for"). I believe I tried asking for them to update the completely erroneous pypi "source code" link to point to that repo and ... well, one can see how well that turned out
