I have inherited some cloud hosted vms, with several services hosted in docker containers on these. Think we server and then DB, both hosted in separate containers. Several (overpriced) vms are involved. Would really like some pointers as to how I can get into these / edit them. Would really like to consolidate. I use proxmox at home and am comfortable in Linux but this is new to me. Any docs / tutorials would be super helpful. Still don’t really understand why the design was done quite like this, so if you have insight on that, please let me know why you would do it this way. Thanks!
If you don’t understand the system, how do you know switching to containers will be an improvement, or even work at all? Are there already published container images for this, or are you also going to learn how to build a container for a custom app?
so the dockers already exist. I want to understand how they were built (I suspect Ansible is involved, but I don’t know how this would work) so I can understand how they interact with one another and then modify.
If you want to know how they’re built, look for
Dockerfilein the code base; that’s usually the file that would create a container image whendocker build …command is used. Perhaps you’d also see something about CI and you’d find a build server some where, too.
