Docker multiline CMD or ENTRYPOINT
I have a really long command line for the default process due to a number of arguments. I think the easiest would be to create a script (for eg.run.sh
) and then call this script in your ENTRYPOINT
or CMD
. I'm wondering if there is a way to make your ENTRYPOINT
or CMD
multiline (the way we write RUN
). For eg.
ENTRYPOINT["/path/myprocess",
"arg1",
"arg2" ]
I was thinking this is a valid syntax since the format is json. However, docker build
throws the error
Step 14 : ENTRYPOINT[
Unknown instruction: ENTRYPOINT[
Is there a way I can split the ENTRYPOINT
to multiple lines?
Solution 1:
It was a typo in the dockerfile. I missed a space
between ENTRYPOINT
and [
. Dockerfile supports multiline ENTRYPOINT
and CMD
by terminating the line with \
, same as RUN
. So, in my case it can be
ENTRYPOINT [ "/path/myprocess", \
"arg1", \
"arg2" \
]
