cant define environment variables based on existing environment variables within container without leaking host environment variables into container about mkdkr HOT 3 CLOSED

so far it looks like the only way we can change envvars within job steps is to have dedicated task shell scripts we execute.

from mkdkr.

"global" variables must be create in two cases:

# global variable are set at start
from-env:
	@$(dkr)
	instance: ubuntu:20.04 -e PATH=$$PATH:/$$HOME/something/i/just/installed
	run: "echo $$PATH"

# create global variable during runtime
from-var-run:
	@$(dkr)
	instance: ubuntu:20.04
	var-run: PATH echo $(PATH):/$(HOME)/something/i/just/installed
	run: "echo $$PATH"

Makefile has two common escapes

$(VAR) -> before run and replace as string at code
$$VAR -> escapes $ character

By default container will add as volume the current directory, if you have bin files in another location, it will not reach the bin file.

PS: export inside container not work, because every run: call open a new bash instance

from mkdkr.
