Use .pkgx.yaml in Dockerfile?

[gaggle]

Is there a way to use the .pkgx.yaml file inside a Dockerfile, so its environment becomes synchronized with the local dev environment? I have a project I'd like to containerize, and I figured I could maybe do something like this:

FROM pkgxdev/pkgx
WORKDIR /app
COPY .pkgx.yaml .
RUN dev

But that actually outputs:

$ docker build --progress=plain .
#8 [build 4/4] RUN dev
#8 sha256:a66705348c4597320598f745464945e2efab1513b3a85c1d9697ae7963eb30a6
#8 0.181 /bin/sh: 1: dev: not found
#8 ERROR: executor failed running [/bin/sh -c dev]: exit code: 127
------
 > [build 4/4] RUN dev:
------

Am I abusing/misunderstanding how pkgx wants to work with a container? The documentation page seems to suggest we can build our own dependencies using RUN env +node@16, but then I'd be replicating my .pkgx.yaml dependencies so I figured maybe the dev command would/should work?

Likely a consequence of this: #769 (comment).
Maybe:

RUN eval "$(pkgx --shellcode)" && dev

?

yes, typing dev will work with the next release 1.0.1 (today I hope).

In the meantime the shellcode for dev is eval "$(pkgx --internal.activate $PWD)" if you like, edit or yes @jhheider’s example is the endorsed route.
