I have a CircleCI configuration file that looks like
so:
# Customize test
commands
test:
override:
- docker run -e VAR1=$VAR! -e
VAR2=$VAR2 -e $VAR3-$VAR3 --entrypoint python my_image:latest -m unittest discover -v -s
test
How can I break
up the docker run
command into multiple lines
like:
docker run \
-e
VAR1=$VAR! \
-e VAR2=$VAR2 \
-e $VAR3-$VAR3
\
--entrypoint python my_image:latest \
-m unittest discover -v -s
test
I've tried using
the |
operator for yaml, but CircleCI was unable to parse
because it expects override
to be a
list.
# Customize test
commands
test:
override: |
docker run
\
-e VAR1=$VAR! \
-e VAR2=$VAR2 \
-e $VAR3-$VAR3
\
--entrypoint python my_image:latest \
-m unittest discover -v -s
test
Using this
href="https://stackoverflow.com/questions/3790454/in-yaml-how-do-i-break-a-string-over-multiple-lines">answer
which details the various ways to break up a string over multiple lines in yaml, I was
able to deduce a solution which works
nicely.
Note the use of the
>-
operator in the override
section.
test:
override:
- >-
docker run
-e VAR1=$VAR!
-e VAR2=$VAR2
-e $VAR3-$VAR3
--entrypoint python
my_image:latest
-m unittest discover -v -s
test
This generates a
nice single-line command
of:
docker run -e VAR1=$VAR! -e
VAR2=$VAR2 -e $VAR3-$VAR3 --entrypoint python my_image:latest -m unittest discover -v -s
test
