The ``latest`` tag is implicitly added by Docker when no tag is specified. - ``idf.py build``: runs this command inside the container. +.. note:: + + When the mounted directory, ``/project``, contains a git repository owned by a different user (``UID``) than the one running the Docker container, git commands executed within ``/project`` might fail, displaying an error message ``fatal: detected dubious ownership in repository at '/project'``. To resolve this issue, you can designate the ``/project`` directory as safe by setting the IDF_GIT_SAFE_DIR environment variable during the docker container startup. For instance, you can achieve this by including ``-e IDF_GIT_SAFE_DIR='/project'`` as a parameter. Additionally, multiple directories can be specified by using a ``:`` separator. To entirely disable this git security check, ``*`` can be used. + To build with a specific Docker image tag, specify it as ``espressif/idf:TAG``, for example: .. code-block:: bash diff --git a/tools/docker/entrypoint.sh b/tools/docker/entrypoint.sh index 7cf15f1917..513b3ba00d 100755 --- a/tools/docker/entrypoint.sh +++ b/tools/docker/entrypoint.sh @@ -1,6 +1,20 @@ #!/usr/bin/env bash set -e +# IDF_GIT_SAFE_DIR has the same format as system PATH environment variable. +# All path specified in IDF_GIT_SAFE_DIR will be added to user's +# global git config as safe.directory paths.
