use Posit Package Manager for faster binary installs in Docker

[cjyetman]

Setting https://packagemanager.posit.co/cran/__linux__/focal/latest as the default CRAN repo will allow the R package installs in Docker to be much faster since it provides binaries for Linux.

⚠️ However, currently arm64 binaries are only available for Debian.

Is this interesting also for https://github.com/RMI-PACTA/workflow.transition.monitor and friends?

[cjyetman]

already used in workflow.transition.monitor
https://github.com/RMI-PACTA/workflow.transition.monitor/blob/main/Dockerfile#L29-L30

[jdhoffa]

Woops! Didn't even look, sorry

[cjyetman]

tagging as blocked in consideration that #112 may soon be merged making this a non-optimal change

[AlexAxthelm]

the Rocker images are all Debian, aren't they?

yes, you're right (I think)
https://rocker-project.org/images/

weird, I think I got confused because workflow.transition.monitor uses
https://github.com/RMI-PACTA/workflow.transition.monitor/blob/db0c750aee92d17ddc94a2762821ef4980d9f17e/Dockerfile#L29

ARG CRAN_REPO="https://packagemanager.posit.co/cran/__linux__/jammy/2023-10-30"

but also based on rocker 🤔

[AlexAxthelm]

I'm guessing they're calling it by the Ubuntu name 22.04 - Jammy Jellyfish, which is a derivative of Debian 11 (Bookworm).

[cjyetman]

maybe, but it seems like https://packagemanager.posit.co/cran/__linux__/bookworm/latest would be a better option (which is an actual, legitimate option)

[AlexAxthelm]

Oh, I had it backwards. the R versioned stack (including r-ver) is based on ubuntu, but the r-base stack builds on debian.

https://rocker-project.org/images/

[cjyetman]

the Rocker images are all Debian, aren't they?

yes, you're right (I think) https://rocker-project.org/images/

actually, it's mixed...

for rocker/r-ver and those that build on it...

This stack builds on stable Debian releases (for R versions <= 3.6.3) or Ubuntu LTS (for R versions >= 4.0.0).

for rocker/r-base and those that build on it...

This stack builds on debian:testing and Debian unstable repo. Use this stack if you want access to the latest versions of system libraries and compilers through apt-get.

Different issue though, why are we using latest, rather than date pinning?

🤷🏻 @jdhoffa created the Dockerfile in this repo

but to be fair... I am less concerned about package versions in this repo than I am in the TM repo

[jdhoffa]

answer is: I made it latest and never changed it.

I see no problem with yall pinning it to whatever you wish :-)
