Trying to get asdf working in docker, this example is useful to get rid of all the hacks:

Also trying to get podman to run faster, podman info gives storage of vfs. Apparently overlayfs is faster, so I set it like so:

functions $ cat ~/.config/containers/storage.conf
[storage]
  driver = "overlay"

https://docs.oracle.com/en/operating-systems/oracle-linux/podman/podman-ConfiguringStorageforPodman.html#configuring-podman-storage

And then I had to podman system reset.

Wow with this change using cached images is instantaneous! Hooray!

Also I'm passing --network host. Not sure if that's doing anything.

Github actions for weave are stuck in queue, no surprise for a free service. Would like to run them locally, perhaps using act: https://github.com/nektos/act

Should incorporate this into the readme somehow, but to run the python server from a podman container the command is:

docker run -i -t -p 5000:5000 (last-image-built) pipenv run gunicorn server:app -b :5000

Ok I have that command as part of a makefile. The workflow isn't totally smooth since this rebuilds the frontend which takes about 15 seconds; ideally the dev server would start in the container with some sort of port mapping... but here's the makefile.

.PHONY: run

all:
	podman build .

run:
	export IMAGE_ID=$(shell podman images --format "{{.ID}} {{.CreatedAt}}" | sort -rk 2 | head -1 | cut -d ' ' -f 1); \
	docker run -i -t -p 5000:5000 $$IMAGE_ID pipenv run gunicorn server:app -b :5000

usage:

make

make run
