Re: [rdf4j-dev] workbench+server image on hub.docker eclipse
If you are using docker on windows or Mac with virtual box you need to open the port there. That could be the issue.

Hi Bart,

I finally got around to taking this for a test spin, great that we can start deploying on DockerHub!

Unfortunately, I'm stuck in actually getting it to work. I can pull the image and start the container easily enough, but no joy on actually seeing the Workbench when accessing http://localhost:8080/rdf4j-workbench. The logs in the container don't show anything (catalina.out is just empty). 

What I did:

docker pull eclipse/rdf4j-workbench:2.4.2-testing1
docker run -d -p 8080:8080 -e JAVA_OPTS="-Xms1g -Xmx4g" -v data:/var/rdf4j -v logs:/usr/local/tomcat/logs eclipse/rdf4j-workbench:2.4.2-testing1

After I've done this, docker ps shows:
                                                                                                                     
CONTAINER ID        IMAGE                                    COMMAND             CREATED             STATUS              PORTS                    NAMES
fb11c037a403        eclipse/rdf4j-workbench:2.4.2-testing1   "catalina.sh run"   11 minutes ago      Up 5 minutes        0.0.0.0:8080->8080/tcp   cranky_turing

But opening http://localhost:8080/rdf4j-workbench on my machine shows an error. In fact it's a very odd error as it says "localhost didn't send any data". Curling to it gives this:

curl: (52) Empty reply from server

Any idea what might be the problem?

Cheers,

Jeen

Good point, seems like the tomcat image is indeed root… I’ll create a tomcat user.

 

Best regards

Seems quite decent Bart :)

 

The only thing I know that’s worth double checking is if tomcat is installed as root or not in the base image. Even in docker it’s a good idea to not run things as root.

Hi Håvard,

 

The Dockerfile itself resides in https://github.com/eclipse/rdf4j-tools/tree/develop/assembly/src/main/dist/docker

Hi Bart,

 

Where is the source for the dockerfile?

Hi,

 

with some help from the Eclipse team (since they manage the eclipse organization on hub.docker.com),

I’ve added the Workbench+Server docker from eclipse/rdf4j-tools/tree/master/assembly/src/main/dist/docker

 

https://hub.docker.com/r/eclipse/rdf4j-workbench/

 

I’ve used the tag 2.4.1-testing, feedback is welcome of course.

 

Two things that can be improved :

  • provide a tomcat username/password when starting the docker image
  • configure HTTPS

 

(and/or maybe consider using Eclipse Jetty instead, since the server pom already includes a dependency on jetty-server…)

 

Best regards

 

Bart
