I have this error:

I don't know why, but Yer another Docker Plugin can provide the slave container.

I have this in settings:

As you can see i put the same docker image than i have in my terminal: jenkins_slave_1.

I tried with jenkins_slave but doesn't works.

I don't know what have i wrong.

I'm using docker 1.12.1 and jenkins 2.23, with lastest Yer another Docker Plugin.

And not, isn't connection problem, see:

I have this Dockerfile for jenkins-slave image:

That's mean that daemon doesn't see this image. If you are making slave from compose, then it probably expected to be a static slave (not for dynamic provisioning via yad-plugin).

[KostyaSha]

Try replace image with kostyasha/jenkins-slave:full For JNLP launcher you should alse ensure that jenkins hostname will be accessible from container.

[SalahAdDin]

Ok:

Error during callback
com.github.kostyasha.yad_docker_java.com.github.dockerjava.api.exception.InternalServerErrorException: {"message":"Error parsing reference: \"kostyasha:jenkins-slave:full \" is not a valid repository/tag"}

Now i have this.

[KostyaSha]

kostyasha/jenkins-slave:full

[SalahAdDin]

Wait a minut com.github.kostyasha.yad_docker_java.com.github.dockerjava.api.exception.NotFoundException: {"message":"No such image: kostyasha/jenkins-slave:latest"}.

[KostyaSha]

Why latest? You didn't set tag.

[SalahAdDin]

Wow, this is bad, very bad:

com.github.kostyasha.yad_docker_java.com.github.dockerjava.api.exception.NotFoundException: {"message":"No such image: kostyasha/jenkins-slave:full"}

[KostyaSha]

https://hub.docker.com/r/kostyasha/jenkins-slave/tags/

[KostyaSha]

So it seems that your docker-engin is bad and has no network (either wrong dns) and can't download image. But initially your issue was because of missing image. Are you trying to follow some docs?

[SalahAdDin]

But, i don't understand why do you say that hasn't network, you can see that test connections are good, none errors.

Which docs say you? I follow this tutorial: https://engineering.riotgames.com/news/jenkins-ephemeral-docker-tutorial But only the part for create a new job.

And i follow this tutorial: https://github.com/maxfields2000/dockerjenkins_tutorial/tree/master/jenkins2 This for this plugin, because official docker-plugin doesn't works with Docker 1.12.1.

[KostyaSha]

Where is your compose file? Didn't you change jenkins-slave to jenkins_slave naming?

[SalahAdDin]

Oh man, you don't sleep? Me too,

Thanks for your help!

Here my compose file:

data:
 build: jenkins-data
master:
 build: jenkins-master
 volumes_from:
  - data
 ports:
  - "50000:50000"
nginx:
 build: jenkins-nginx
 ports:
  - "80:80"
 links:
  - master:jenkins-master
slave:
 build: jenkins-slave

[KostyaSha]

@SalahAdDin 1) referenced doc suggests to use "pull never" so when you placed my dockerhub image it probably didn't try download it. So maybe your docker daemon is fine. Try set "pull once" strategy in slave template settings. 2) To ensure that you really has your custom image jenkins_slave_1 run docker images command

[SalahAdDin]

And, well, i don't know but now i have and advance, i have serious problems with my custom jenkins image.

And here my configuration:

Good, my advances are this: Yes, i have a new node, but, he doesn't connect.

Trying search in log files, i haven't found any report, and in log within new node i have this:

Starting connection command for 605f28691ad4a5631a56a89576a2243d39a2a5bf83762c64e399c0ee3dee241d

What is my error now?

[SalahAdDin]

Maybe doesn't works because in testing in local environment, right?

[KostyaSha]

As super stupid question, could you remove spaces from cloud name?

[SalahAdDin]

No, had i? Have i put a cloud name without spaces?

[SalahAdDin]

Well, i change Cloud Name to DockerHost and relaunching the slave node i get this:

It creates other node that have the same performance: I see this in node page: And see this when i tried relaunch again. And see this when i see logs:

Until now, doesn't works.

[joeybdub]

Did you resolve this issue?

[SalahAdDin]

Not yet.

[joeybdub]

Mine was the expose port and the command to start the connection were not installed on docker image I was using. I resolved these and its working for me but not sure you have the same issue. Sorry if this doesnt help!

[SalahAdDin]

Can you provide me more information about your problem and your solution? please.

[joeybdub]

I had a similar issue to you: ERROR: Unexpected error in launching an agent. This is probably a bug in Jenkins.

So while googling I seen this issue. The problem I had was related 2 missing configs in my image.

1. The docker image wasnt starting with sshd. This was required in the dockerfile at build time but you can add to a container and commit also. /usr/sbin/sshd -D

The second issue I had was that my images were not exposing port 22 when the containers started. Again at build time was missing... EXPOSE 22 You can check this with docker inspect command.

[KostyaSha]

Or use docker JNLP launcher instead of ssh with right configured jenkins master hostname/address it should work without image modifications for images that has java and curl/wget.

[joeybdub]

docker JNLP launcher doesnt work for me... I think its due to "COMMAND" "/bin/bash -cxe 'cat " but I havent had time to spend debugging!

[KostyaSha]

it was relaxed to sh in latest versions.

[joeybdub]

Thanks. This on path to production I dont want the latest and greatest yet! But appreciate the info!

[SalahAdDin]

I'm waiting for riot games Jenkins docker tutorial update, his author said that he will update it and change ssh by JNLP.

[danieleagle]

@SalahAdDin, I was waiting for an updated tutorial as well. Instead of waiting, I decided to create one myself: https://github.com/GetchaDEAGLE/jenkins-ephemeral-cicd. Hopefully this is of use to you.
