How to show the full (not truncated) "CREATED BY" commands in "docker history" output?

How can I show the full command in the third column (CREATED BY) in the docker history output?

$ $ docker history python
IMAGE          CREATED       CREATED BY                                      SIZE      COMMENT
69ee9abe2bda   5 weeks ago   CMD ["python3"]                                 0B        buildkit.dockerfile.v0
<missing>      5 weeks ago   RUN /bin/sh -c set -eux;   wget -O get-pip.p…   10MB      buildkit.dockerfile.v0
<missing>      5 weeks ago   ENV PYTHON_GET_PIP_SHA256=22b849a10f86f5ddf7…   0B        buildkit.dockerfile.v0

The CREATED BY is truncating/abbreviating the commands which makes it hard to reconstruct the original Dockerfile. How do I get the full CREATED BY commands?

Solution

  • Use the docker history --no-trunc option to show the full command.
