Body

I have this Dockerfile:

FROM mcr.microsoft.com/devcontainers/go:1.23

RUN sudo apt-get update \
    && sudo apt-get install -y \
    && apt install python3.11-venv -y \
    && python3 -m venv venv \
    && venv/bin/pip install jupyterlab

and this devcontainer.json file:

    "build": {
        "dockerfile": "Dockerfile"
    },
    "postCreateCommand": ". venv/bin/activate && jupyter-lab --no-browser",

the postCreateCommand fails:

/bin/sh: 1: .: cannot open venv/bin/activate: No such file

how can I activate the virtual environment successfully?

is that chatgpt generated? anyway, it didn't work

[paololazzari]

this doesn't work either:

"postCreateCommand": "venv/bin/python -m jupyterlab --no-browser",

/bin/sh: 1: venv/bin/python: not found

Having the venv in the home directory fixed it:

FROM mcr.microsoft.com/devcontainers/go:1.23

RUN sudo apt-get update \
    && sudo apt-get install -y \
    && apt install python3.11-venv -y \
    && python3 -m venv /home/vscode/venv \
    && /home/vscode/venv/bin/pip install jupyterlab

"postCreateCommand": "/home/vscode/venv/bin/python -m jupyterlab --allow-root --no-browser",
