podman/test/compose

Tests for docker-compose

This directory contains tests for docker-compose under podman.

Each subdirectory must contain one docker-compose.yml file along with all necessary infrastructure for it (e.g. Containerfile, any files to be copied into the container, and so on.

The test-compose script will, for each test subdirectory:

• set up a fresh podman root under an empty working directory;
• run a podman server rooted therein;
• cd to the test subdirectory, and run docker-compose up -d;
• source tests.sh;
• run docker-compose down.

As a special case, setup.sh and teardown.sh in the test directory will contain commands to be executed prior to docker-compose up and after docker-compose down respectively.

tests.sh will probably contain commands of the form

 test_port 12345 = 'hello there'

Where 12345 is the port to curl to; '=' checks equality, '~' uses expr to check substrings; and 'hello there' is a string to look for in the curl results.

Usage:

$ sudo test/compose/test-compose [pattern]

By default, all subdirs will be run. If given a pattern, only those subdirectories matching 'pattern' will be run.

If $COMPOSE_WAIT is set, test-compose will pause before running docker-compose down. This can be helpful for you to debug failing tests:

$ env COMPOSE_WAIT=1 sudo --preserve-env=COMPOSE_WAIT test/compose/test-compose

Then, in another window,

# ls -lt /var/tmp/
# X=/var/tmp/test-compose.tmp.XXXXXX <--- most recent results of above
# podman --root $X/root --runroot $X/runroot ps -a
# podman --root $X/root --runroot $X/runroot logs -l
