"Can not connect to Ryuk" on CircleCI 2.0 with Docker executor

Overview

I’m trying to run a build with Testcontainers on CircleCI 2.0 with the Docker executor (not the Machine executor, as recommended by the docs, see below). The build fails with java.lang.IllegalStateException: Can not connect to Ryuk.

My question: Is there a chance this will work?

On using CircleCI Docker executor vs Machine executor

The Testcontainers docs suggest using the machine executor type in CircleCI instead of docker: https://www.testcontainers.org/ci/ci.html#circleci-20

I have not tested this, but I assume it would work.

However, I am trying to avoid using the machine executor, since it has some limitations with startup time and custom images, and also “may require additional fees in a future pricing update” (source).

The docker executor (aka “the new one”) does support using Docker itself in the build (to build images, etc), by using the “Remote Docker” feature, calling the setup_remote_docker command in the config file.

Full log of my investigation

The Docker runner in CircleCI communicates the Remote Docker host location to the running processes in the build by setting the usual env variables ($DOCKER_HOST, etc).

Testcontainers recognizes this configuration and reports as follows:

2018-12-12 21:30:51,892 INFO  o.t.dockerclient.DockerClientProviderStrategy  - Found Docker environment with Environment variables, system properties and defaults. Resolved: 
    dockerHost=tcp://35.237.241.162:2376
    apiVersion='{UNKNOWN_VERSION}'
    registryUrl='https://index.docker.io/v1/'
    registryUsername='circleci'
    registryPassword='null'
    registryEmail='null'
    dockerConfig='DefaultDockerClientConfig[dockerHost=tcp://35.237.241.162:2376,registryUsername=circleci,registryPassword=<null>,registryEmail=<null>,registryUrl=https://index.docker.io/v1/,dockerConfigPath=/home/circleci/.docker,sslConfig=LocalDirectorySSLConfig{dockerCertPath=/tmp/docker-certs117526089},apiVersion={UNKNOWN_VERSION},dockerConfig=<null>]''

It seems that Testcontainers is indeed able to work with this remote Docker host, since it reports having downloaded the Ruyk image:

2018-12-12 21:30:53,320 DEBUG c.g.d.core.command.PullImageResultCallback     - PullResponseItem[stream=<null>,status=Status: Downloaded newer image for quay.io/testcontainers/ryuk:0.2.2,progressDetail=<null>,progress=<null>,id=<null>,from=<null>,time=<null>,errorDetail=<null>,error=<null>,aux=<null>]

It also shows lots of ResponseItem.ProgressDetail logs before that while downloading the image.

I can check that it indeed download the image by SSH’ing into the build container as CircleCI allows and running docker images:

circleci@1fc8c94e899d:~$ docker images
REPOSITORY                    TAG                 IMAGE ID            CREATED             SIZE
quay.io/testcontainers/ryuk   0.2.2               527073eb32d1        10 months ago       9.31MB

According to the full log (reproduced below), at time 21:30:53,605, dockerjava issues a start container command, then almost immediately (21:30:53,924) tries to inspect it. Then it hangs for the timeout period, 30 seconds, and spits out the SEVERE error at 21:31:23.

I’ve tried increasing the Ryuk timeout by setting ryuk.container.timeout to 120 seconds as suggested in #581. The timeout did change, because the build hanged for 2 minutes before closing with the same exception.

It seems the start command never ran, because nothing is listed when I run docker ps -a inside the build container.

I have also tried to debug Ruyk independently, running the command below as suggested by @jmaicher in #572:

docker run -p8080:8080 -v /var/run/docker.sock:/var/run/docker.sock --name ryuk -P -d quay.io/testcontainers/ryuk:0.2.2

It started, but then quits after waiting for the initial connection:

2018-12-12T21:46:29.814640890Z 2018/12/12 21:46:29 Starting on port 8080...
2018-12-12T21:47:29.818668885Z panic: Timed out waiting for the initial connection

2018-12-12T21:47:29.818721719Z 	/go/src/github.com/bsideup/moby-ryuk/main.go:92 +0xe1e

I believe it says that it was able to the Docker Engine, since if I start without mapping the socket it exits immediately with panic: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?. It does not say if it’s indeed reachable, since I believe Ryuk listens for messages sent by the ResourceReaper class in Testcontainers, which wasn’t running at the time.

I have also tried to check for port connectivity, and indeed CircleCI seems to close ports. I ran the nginx image mapping port 80 to 30080, and tried curl -v 35.237.241.162:30080/, which just hangs there. So, Ryuk working in this scenario may be a problem even if the container did start.
