what are your thoughts around docker cp

my thoughts are - oh nice! I've never used that 😎

Lemme give that a whirl. The case that I can think of that I want to make sure doesn't get wonky is we'd need the guidance to prob match up to copy into /data so the tarball will still ultimately land in the persistent dir, else if you docker-compose down then the db/everything else expecting the tarball would still live on and then might go sideways on start up next time.

I concur that keeping things as simple as possible especially around what crosses the host boundaries is ideal.

Nice! It's worth noting that RSPM also "caches" the tarball, so once you have imported it, you can actually dispense with it 😄 We don't make that very clear in our docs, as far as I can tell, but if you are persisting the database and the data directory then there is really no need to keep track of the tarball - ephemeral storage is just fine 😄

that is definitely an interesting tidbit to know!

round 2 - trying flow with docker cp:

built demo1 pkg in the rsw container:

we see demo1_0.1.0.tar.gz kicked out in data/rsw/rstudio

data/rsw/rstudio🔒 on  rspm_mnt [!]
❯ ls
R  demo1  demo1_0.1.0.tar.gz

find container id:

❯ docker ps
CONTAINER ID   IMAGE      
1b6f4f5fc669   rstudio/rstudio-package-manager:2021.12.0-3  ...

copy from host into rspm image:

docker cp data/rsw/rstudio/demo1_0.1.0.tar.gz 1b6f4f5fc669:/tmp

cool deal its there:

❯ docker exec -it 1b6f4 /bin/bash
root@1b6f4f5fc669:/# ls /tmp
demo1_0.1.0.tar.gz

root@1b6f4f5fc669:/# rspm create source --name=demopkgs
Source 'demopkgs':
  Type:  Local
root@1b6f4f5fc669:/# rspm add --source=demopkgs --path='/tmp/demo1_0.1.0.tar.gz'
Added package '/tmp/demo1_0.1.0.tar.gz'.
root@1b6f4f5fc669:/# rspm create repo --name=demopkgs --description="demo package repo"
Repository: demopkgs - demo package repo - R
root@1b6f4f5fc669:/# rspm subscribe --repo=demopkgs --source=demopkgs
Repository: demopkgs
Sources:
--demopkgs (Local)

and looks like we're in business:

@colearendt docker cp worked like a charm - renamed the PR and updated the docs to show the new flow. Demonstration of e2e steps + screenshots also in PR above
