deploy
python virtualenv
Because ansible setups have requirements towards used python versions, libraries etc, we use a separate python virtualenv.
export VENV_PATH='/tmp/venv'
# create the env
$ python -m venv "${VENV_PATH}"
# activate it
$ . "${VENV_PATH}/bin/activate"
# install pip dependencies
pip install -r ansible-runtime/requirements.txt
kick off the deployment
assumptions:
- you have initialized and activated the venv as described above
- the current user has ssh access to
localhost - the current user can access the docker socket at
/var/run/docker.sock
$ cd ansible
$ ansible-playbook -i inventory.yaml playbook.yaml
This deploys three containers and a network. List them:
# quick and dirty:
docker ps -a | grep userlike
# or with something like this:
docker ps --format json -a | yq -p json -ojson 'select(.Names|test("userlike-.*"))'
And confirm the routing works as expected:
curl -k https://localhost:8443/ # shall return one/two backend alternating responses
curl -k https://localhost:8443/one # shall only return "one" responses
curl -k https://localhost:8443/two # shall only return "two" responses
