Issues running regtest docker image

Browser
#1

Solutions to problems that I encountered using the regtest docker container.

1. Container shutting down after failure to fill address with bitcoin.

Error trace:

Fill mr6nrMvvh44sR5MiX929mMXP5hqgaTr6fx (cRH8tAZw6gSbewktG2Ajeq7KwFQ29Q7yADrfwBMxYHnMUvTxxNx8) with 50

    raise err
socket.error: [Errno 99] Cannot assign requested address

Solution:

Pull latest image.
docker pull quay.io/blockstack/integrationtests:develop

Prune old stopped containers
docker container prune

2. Docker container shuts down after waiting for Blockstack API process to start

This is due to lingering pid files from previous runs which prevents the API process from starting up.

Solution:
Start the container without mounting /tmp by removing the -v /tmp:/tmp option from the docker start command.

IMAGE=$(docker run -dt -p 6270:6270 -p 16269:16269 -p 18332:18332 -e BLOCKSTACK_TEST_CLIENT_RPC_PORT=6270 -e BLOCKSTACK_TEST_CLIENT_BIND=0.0.0.0 -e BLOCKSTACK_TEST_BITCOIND_ALLOWIP=0.0.0.0/0 quay.io/blockstack/integrationtests:develop blockstack-test-scenario --interactive 2 blockstack_integration_tests.scenarios.browser_env)
