Maybe this is a little bit off-topic. I would like to ask how you manage your dockerfile.

I have a git repo hosting my configurations (docker-compose, traefik, etc). Then, I have a python script that reads data from JSON, renders the placeholder inside these files (the {{replace_me}}) by an actual value and outputs them to another directory. Finally, I cd to that directory and run docker-compose up -f .... (This approach takes inspiration from the terraform templatefile)

That JSON file is generated by some terraform code, along with terraform code for other stuffs (storage bucket, vps, dns, etc).

It works well for me so far. Especially for:

  • templating traefik toml configuration (I like it a lot more than the label approach).
  • secret in the docker env file (so my docker.env file has the form of secrect={{secret}}.

I know most templating docker part can be replaced by directly interpolating with environment variables but I don’t really like it because it seems environment variables are not persistent.

Do you have any suggestions for my workflow ? I am always feel a litte bit off about this approach.

Edit: Thank you for your suggestions. I will try k8s for edge computing and if it does not work really well, I will stick with my current approach.

    Man you’re so close to Helm at this point, for me if I’m getting into templating I’d rather go on full Kubernetes and Helm

      I know about Helm but I don’t need k8s features and my VPS is just too weak for k8s I think :/

        Honestly look into k3s or other “distros” of k8s. There are some versions of the orchestrator made for edge computing that are quite slim in their size and gives you all the perks of the k8s api layer.
