I am trying to get started in the DevOps Field by setting up a small server currently with Virtualbox, later on for a small team. For my basic setup I plan to use gitea as self-hosted git and Jenkins as CICD tool which also provides a lot of extensions.
The server OS I chose is RHEL 8 since the systems on which I will setup up my DevOps system in a distant future will use this OS.
Now I find a lot of sources in the internet that point me to install both tools using containers combined with an orchestration tool like kubernetes. I have a certain degree of theoretical understanding of docker and kubernetes and also experimented a little bit with both tools.
My research also provided me information on the advantages of running Jenkins in a pod:
- only required in certain situations
- sometimes several instances of Jenkins for different projects can be required to run in parallel
At least were that the points that I found on different blogs websites that discussed this topic for Jenkins.
For Gitea I was not able to determine reasons why it should be run in container inside a pod in kubernetes but there is a helm-chart managed by the community of it. Also I found several sources on the internet telling me helm-charts are bad, don't use them.
To build, test and deploy applications (which will be Rest applications with react/node-js frontend and different backends) I will use container and kubernetes to orchestrate the container.
Could you help me understand why I should decide for or against containers/pods for the different applications and maybe even provide reliable sources, since most information I found are just opinions spread through the internet.
