Start database container with mounted config file in Github actions workflow - github

Question

I'd like to run some integration tests against a real database, but I fail to start an additional container (for the db), because I need to mount a config file that is in my repo before it is starting up.
This is how I use the database on my local computer (docker-compose):
gremlin-server:
image: tinkerpop/gremlin-server:3.5
container_name: 'gremlin-server'
entrypoint: ./bin/gremlin-server.sh conf/gremlin-server-config.yaml
networks:
- graphdb_net
ports:
- 8182:8182
volumes:
- ./conf/gremlin-server-config.yaml:/opt/gremlin-server/conf/gremlin-server-config.yaml
- ./conf/tinkergraph-empty.properties:/opt/gremlin-server/conf/tinkergraph-
I guess I cannot use a service container as the code is not available at the time the service container is started, therefore it won't pick up my configuration.
That's why I tried to run a container within my container using --network host (see below) and the container seems to be running fine, still I'm not able to curl it.
- name: Start DB for tests
run: |
docker run -d \
--network host \
-v ${{ github.workspace }}/dev/conf/gremlin-server-config.yaml:/opt/gremlin-server/conf/gremlin-server-config.yaml \
-v ${{ github.workspace }}/dev/conf/tinkergraph-empty.properties:/opt/gremlin-server/conf/tinkergraph-empty.properties \
tinkerpop/gremlin-server:3.5
- name: Test connection
run: |
curl "localhost:8182/gremlin?gremlin=g.V().valueMap()"
According to the documentation about the job context the id of the container network should be available ({{job.container.network}}) but is empty if you don’t use any job-level service or container.
Any ideas what I could try next?

This is what I ended up with: I'm now using docker-compose to run the integration tests (on my local computer as well as on GitHub Actions). I'm just mounting the entire directory/repo in the test container. Pulling the node:14-slim delays the build by some seconds, but I guess it's still the best option:
version: "3.2"
services:
gremlin-server:
image: tinkerpop/gremlin-server:3.5
container_name: 'gremlin-server'
entrypoint: ./bin/gremlin-server.sh conf/gremlin-server-config.yaml
networks:
- graphdb_net
ports:
- 8182:8182
volumes:
- ./data/:/opt/gremlin-server/data/
- ./conf/gremlin-server-config.yaml:/opt/gremlin-server/conf/gremlin-server-config.yaml
- ./conf/tinkergraph-empty.properties:/opt/gremlin-server/conf/tinkergraph-empty.properties
- ./conf/initData.groovy:/opt/gremlin-server/scripts/initData.groovy
test:
image: node:14-slim
working_dir: /app
depends_on:
- gremlin-server
networks:
- graphdb_net
volumes:
- ../:/app
environment:
- NEPTUNE_CONNECTION_STRING=ws://gremlin-server:8182
command:
yarn test
networks:
graphdb_net:
driver: bridge
and I'm running them like this in my workflow:
- name: Spin up test environment
run: |
docker compose -f dev/docker-compose.yaml pull
docker compose -f dev/docker-compose.yaml build
- name: Run tests
run: |
docker compose -f dev/docker-compose.yaml run test
It's based on #DannyB's suggestion and his answer here so all props go to him.
