I took a look at Dashy, I think I see the confusion. If you are looking at this article, then yes they mention Code Server, but that's purely in the context of using Dashy in a non-docker context. But to be honest, any text editor works.
But I think that's a red herring. That in itself has nothing to do with docker.
What you'll need to do, once you understand the fundamentals of running docker, pull images, start a container based on an imagine, is to expose a docker volume that points to
/public/conf.yaml. A docker volume ensures that the file or directory it's mapped to in the container is available and persists outside of the container. This allows you to persist files and directories without losing them once the container stops or restarts.Once the volume is exposed, then you can use your favorite text editor to update the dashy config file. Code Server is fine, powerful, but overkill.
But first, try getting familiar with pulling, starting stopping docker images using the cli. Gotta start there first before tinkering with docker parameters like volumes.
Yeah Dashy isn't really important to me, it's just another fun project to learn more about Docker. However, what I learned is that I don't know shit about what I'm doing lol. It proved to be a great tool at exposing my absolute ignorance of something I thought I was getting a good grasp on.
Yeah I think I'm gonna shit can Portainer and go through that LinkedIn course someone else posted. Thanks for your insight.
Portainer is definitely useful (I use it on a daily basis), but probably a bad place to start...
I started with the following progression:
Good luck in your journey!
Docker-compose got it done. Once I learned about Volumes and using compose to pass in volumes from other instances I was able to pass in a directory with a custom yaml to the Dashy container then pass the same directory into the code-server container and both are working as I expected they should. Compose and volumes were the missing pieces. I also learned that stacks is how to use compose in Portainer. Not sure why they felt the need to change the naming but it works.
That is AWESOME! Congrats!
Yes that's right, portainer stacks equate to compose.. I might be wrong, but I remember reading somewhere a while back that they (and other container orchestration tools) were not permitted to reference "Docker" or its products (including compose) due to legal and licensing restrictions by Docker.
Not to the level of Reddit, but Docker has its fair share of questionable business decisions.
