Should I be learning docker compose instead of relying on dockStarter to manage my containers? I got portainer up, should I just use that to manage my stack?
I’m committed this summer to finally learning docker. I’m on day 3 and the last puzzle piece is being able to access qbittorrent locally while running the container through the vpn.
May I ask you why?
Aside from the myriad issues it has on its own, the easiest answer is: it doesn’t scale on multiple machines and instances.
Example: I have 10 services in a compose file, and I need each service to scale independently across multiple servers. Which is easier, more reproducible, and reliable: controlling the docker compose state across many instances, or communicating with a central management service with one command to do it all for me?
What you need then is swarm compose, that can run any service in global mode (in all nodes all the time) or scale mode.
No, then you’re just orchestrating the service level stuff, and nothing else. Docker’s tools will never compare to cluster scaling efforts where the entire horizontal layer to be scaled can be orchestrated from the instance up to containers.
not sure I understand you, in docker swarm your containers are started on n number of works from a single compose file on a manager. you can add any number of work nodes to scale your service as needed
N number of EXISTING nodes. Proper container orchestration platforms handle all the provisioning of instances, scaling of services, IAM…etc.
Docker Swarm (and all Docker tools) only handle…Docker.
Swarm is another thing I would never recommend in production.
That’s not container orchestration, that’s infrastructure orchestration. Depending on your use case docker swarm could just the right tool for the job.
You’ve been using Aws and they will happily let you add more nodes to your container runner of choice
No, it’s container orchestration. As-in “I orchestrate all the scaling needed to run and scale the containers”.
