I need to re-engineer a full offline installer that's been cobbled together in bash and has become brittle very quickly.

There are 2 parts to this, and I'm hoping there's something that can essentially handle both parts. Everything I know or have investigated doesn't handle full end to end.

Setting the stage at the customers location:

  • Customer is asked to provide a centos VM. All customers will provide the VM in one of the following states:
    • Installed from CD, never connected to the internet
    • Installed from CD, updated using a local "intranet" repo owned by customer
  • Intranet access is always available, but there is no route from the VMs to the internet as per customer company policy.

Part 1 - Creating the installer:

Some sort of tool or framework that can generate a package that includes everything necessary to take an VM as described above to operational.

Include the following components:

  • Docker RPM and all chained RPM dependencies
  • Docker containers
  • Java RPM and all RPM depedencies
  • Artifactory Artifacts
  • Deployment framework used by Part 2 (if independent of part 1 toolset)

Currently Part 1 is done in bash and has the following drawbacks:

  • It needs to explicitly list (currently) all 277 packages to download
  • A bunch of logic to allow incoming parameters to specify the version of each service to pull into the offline installer package
  • Credentials to access and download from private repos (docker, artifactory) stored in plaintext :(
  • manually retagging all downloaded docker images to a "local" registry

Part 2 - Running the installer package:

If there is no tool that can do both Part 1 and Part 2, solutions for just part 2 are much simpler to find (ex: ansible)

Execute the installer package:

  • Create a local RPM repo based on all the RPMs extracted via the installer package
  • Install via yum --enablerepo=local /*rpm (docker, java + all chained dependencies)
  • Copy java artifacts, install system service files and start non-dockerized services
  • Create local docker container repo
  • Call dockerfiles and spin up docker environment
  • Perform service checks and ensure services are running

Evaluated or known tools so far

Chef: Hamstrung in offline. Does not handle part 1. Has no mechanism to pack everything up for offline. Overkill for just deployment from an extracted offline package.

Habitat: Hamstrung in offline (tightly coupled to online repos), handles even less than chef. Effectively claims by design that part 1 can be ignored.

Ansible: Does not handle Part 1 at all. Can likely clean up some of part 2, seems to have ok support for offline but no personal experience with this yet.

  • What specific question do you have? Server Fault is not the place for tool recommendations, pick the set you want and try something. Plus, refactor and/or bug bash on your packaging and deployment project is too broad a scope. – John Mahowald May 15 at 22:22
  • My question would be "Does a tool even exist that meets these requirements?". If it were "should I use tool A or B?" I could see that falling under recommendations and opinions. But at this point, I'm just trying to find out if "A even exists" and what might it be called. Barring that, which stack exchange site would be better than server fault for this? I see there's a DevOps one? – rpwcal May 15 at 22:38
