Some initial commands to setup and run a test container fixture using Docker CLI - for real test code, this should be wrapped in a Python UnitTest class and use docker-py

build-and-run-fixture-docker-container.sh

docker build -t craton-inventory:latest .

# assign a random (ephemeral) port to our localhost's interface for
# the container's 8080; this ensures we are not tying up 8080 for
# testing!
docker run -p 127.0.0.1::8080 -d craton-inventory:latest

# get the container name/uuid along with the exposed port for 8080;
# in the case below, it's sick_lichterman and 32775 respectively
# for real usage, this should be done programmatically using docker-py
docker ps -a

# load the fixture data to complete initial setup
python tools/generate_fake_data.py --url http://127.0.0.1:32775/v1 --user demo --project 1 --key demo

# create a new image based on this running container (sick_lichterman)
# we cannot simply run with the same command since it has some initial setup such as creating
# the mysql database and some initial user data - that's already been created in the container,
# so we will simply have something to startup mysql, wait for it; then start the api service
docker commit --change='CMD  ["tools/docker_test.sh"]' sick_lichterman  craton/functional_test:v1

# now run this new image
docker run -p 127.0.0.1::8080 -d craton/functional_test:v1

# get port mappings, names - again, this should be done programmatically
docker ps -a

docker_test.sh

#!/bin/bash

# subset of container command startup to just ensure mysql + api service is running
# put this in tools/docker_test.sh and chmod a+x on it

/usr/bin/mysqld_safe > /dev/null 2>&1 &

while [[ RET -ne 0 ]]; do
    echo "=> Waiting for confirmation of MySQL service startup"
    sleep 5
    mysql -uroot -e "status" > /dev/null 2>&1
