Socket Exception when building

[cescoffier]

Hi,

I cannot build an image. I get:

[INFO] Building tar: /Users/clement/Projects/vert.x/vertx-microservices-examples/aggregation-http/A/target/docker/vertx-microservices-example/aggregation-http-A/1.0-SNAPSHOT/tmp/docker-build.tar

[ERROR] DOCKER> Broken pipe

Docker is running fine (I'm using a docker-machine).

I'm using a docker machine, my env is:

set -gx DOCKER_TLS_VERIFY "1";
set -gx DOCKER_HOST "tcp://192.168.99.100:2376";
set -gx DOCKER_CERT_PATH "/Users/clement/.docker/machine/machines/dev";
set -gx DOCKER_MACHINE_NAME "dev";

The debug mode does not give much details:

[DEBUG] http-outgoing-6 >> "[write] I/O error: Connection has been shutdown: javax.net.ssl.SSLException: java.net.SocketException: Broken pipe"
[DEBUG] http-outgoing-6: Shutdown connection
[DEBUG] Connection discarded

[ERROR] DOCKER> Broken pipe

Any idea ?

[cescoffier]

Seems to be related with file size. Is there a limit ?

[rhuss]

Good question. How large is your /Users/clement/Projects/vert.x/vertx-microservices-examples/aggregation-http/A/target/docker/vertx-microservices-example/aggregation-http-A/1.0-SNAPSHOT/tmp/docker-build.tar ?

Do you have the project somewhere online so that I can try to reproduce it here (somtimes later this weekend, its family time for now :) ?

[cescoffier]

It;s not that large, something around 30 Mb.

I'm going to provide a git repo where you can reproduce it.

Enjoy your long weekend !

[rhuss]

Thx :) BTW, I've already built swarm apps with the plugin and docker machine which were larger than 90 MBs ....

[cescoffier]

Here is a reproducer: https://github.com/cescoffier/docker-maven-issue-broken-pipe

It's not a size issue.

[rhuss]

The issue was that one tag contains a - (i.e. 1.0-SNAPSHOT) which is not an allowed value by Docker.

I opened #423 for this.

Thanks for reporting ;)

[rhuss]

No, its not the hypen, but sth different with the name. When I set the name explicitely, it works. Strange ...

[rhuss]

Got it: No capital letters are allowed. Did you know this ?

[rhuss]

So simply change your project from 'A' to 'a'. That's it :)

[cescoffier]

Wow.... So many convention. What about a better error message or "name" transformer ?

[rhuss]

We decided to introduce an error in that case (see #423). Clean, simple and no magic. Fix for the use is easy anyway.

BTW, you can use - in version numbers, that was my fault. Only uppercase letters do harm (and of course probably other chars as well unfortunately I couldn't found an exact specification how a name could look like)

[rhuss]

Ok fixed it. Now the error message looks like

[INFO] ------------------------------------------------------------------------

Hope that its a bit clearer now ;-)

Better error message than the docker client! 👍

[cescoffier]

Great thanks @rhuss !

Much better than the original broken pipe.
