Re: [rdf4j-dev] workbench+server image on hub.docker eclipse
Hi Bart,

The AMD image does the trick, I can spin it up and get a running RDF4J Workbench on my macbook. Thanks for that! Btw docker logs on the old image container (after it had been killed) returned nothing.

A manifest would be great, will that also enable people to select :latest instead of a specific version?

Finally I assume we want to build deployment of these images into our pipeline somehow. Can you enlighten me how you push these images? If we can turn it into a maven goal and/or a Jenkins job we can start making this part of our release process. If we have a docker image automatically available for every release we can also do a bit more PR around this way to quickly get a fully fledged RDF database up and running.

Cheers,

Jeen

Hi,

 

Meanwhile I’ve created two new test images, one for ARM64v8 and one for x86-64/amd64.

I’ll have to do some minor tweaking to make it more transparent for the end user (see also https://blog.docker.com/2017/11/multi-arch-all-the-things/),

i.e. a docker manifest to automatically select the correct architecture image

 

The ARM version seems  to work, haven’t tested the intel/amd64 version yet, but you may want to try

 

  docker pull eclipse/rdf4j-workbench:amd64-2.4.2-testing3

 

 

Best regards

 

Bart

Hi Jeen,

 

autch, probably my bad, my docker server is ARM-based, not Intel, so I probably have to push/configure the intel version as well.

Can you execute "docker ps --all" to get the ID of the (not running) container, and then "docker logs <id>" to get some more info ?

 

Thanks

 

Bart

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.

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
