docker for mac compatibility

Hello,

I am beta testing docker 4 mac and when I disable docker-machine my test suite fails with

java.lang.UnsatisfiedLinkError: Could not find library in classpath, tried: [libjunixsocket-macosx-1.8-x86_64.dylib, libjunixsocket-macosx-1.5-x86_64.dylib]
    at org.newsclub.net.unix.NativeUnixSocket.load(NativeUnixSocket.java:81)
    at org.newsclub.net.unix.NativeUnixSocket.<clinit>(NativeUnixSocket.java:112)
    at org.newsclub.net.unix.AFUNIXSocket.<init>(AFUNIXSocket.java:36)
    at org.newsclub.net.unix.AFUNIXSocket.newInstance(AFUNIXSocket.java:50)
    at org.testcontainers.shaded.com.github.dockerjava.jaxrs.ApacheUnixSocket.<init>(ApacheUnixSocket.java:53)
    at org.testcontainers.shaded.com.github.dockerjava.jaxrs.UnixConnectionSocketFactory.createSocket(UnixConnectionSocketFactory.java:65)

The latest version of test containers (1.0.3 at the time of this writing) uses docker-java 2.2.0 (https://github.com/testcontainers/testcontainers-java/blob/2e227e29eded31c0b2d45a5351cc108994327394/core/pom.xml#L20) so I assume it is safe to say that docker-java 2.2.0 is not compatible with docker 4 mac. (I tried adding the dylib to my classpath and got further errors, also the compiled dylib seems hard to find and it feels very cumbersome to have to add it to the classpath manually).

I want to create a bug report to org.testcontainers asking them to upgrade docker-java to a docker4mac compatible version so I checked out the repository and tried to build master using only docker4mac. I first got an error in com.github.dockerjava.client.DockerClientTest which seems to be the integration test. The error was that $HOME/.docker/certs did not exist. After creating that directory, I get the following output :

beforeTest(com.github.dockerjava.client.DockerClientTest)  Time elapsed: 2.359 sec  <<< FAILURE!
javax.ws.rs.ProcessingException: org.apache.http.conn.UnsupportedSchemeException: https protocol is not supported

Caused by: org.apache.http.conn.UnsupportedSchemeException: https protocol is not supported
    at com.github.dockerjava.client.DockerClientTest.beforeTest(DockerClientTest.java:32)

Tests run: 462, Failures: 1, Errors: 0, Skipped: 458

And I am unsure what to conclude, the test failure seems to suggest that the lastest master is not docker4mac compatible either but a single failed test seems surprising …

Can you help me troubleshoot or maybe you already know if master is compatible with docker4mac …

Thanks for your help jean

Just to add to this - I’m using Pycharm by jetbrains on Mac and trying to set up using a remote docker interpreter. I believe Pycharm is using docker-java.

Instead of using docker machine integration, I’m trying to use the “local” docker as provided by the new beta docker functionality (1.11.1-beta10 ), by setting the docker API address in Pycharm to unix:///var/run/docker.sock. This yields the following message:

Cannot connect: java.ws.rs.ProcessingException: Could not
initialise class org.newsclub.net.unix.NativeUnixSocket

Happy to provide more info if it’s of use to anyone.

@gesellix I meant insecure as in cross site scriptable from the browser afaics

@eduardolundgren I have been able to forward the socket to tcp on localhost

socat TCP-LISTEN:2375,reuseaddr,fork UNIX-CONNECT:/var/run/docker.sock &
export DOCKER_HOST=tcp://localhost:2375
unset DOCKER_TLS_VERIFY

This seems to work well since I can cURL in perfectly. Docker cli is also happy. However docker-java doesn’t seem to pick it up yet somehow. Will have to investigate further.
