Failure during build: Host key verification failed after Initializing Git repository

Hi there,

First of all, I’d like to thank for all the help… Also, the UI remake for Jenkins is freaking awesome… It is the best I’ve ever seen around…

Anyway, I’m trying to build using docker-compose as reported before… I still cannot get past from the git fetch due to a “Host key verification failed.”…

According to the http://stackoverflow.com/questions/15174194/jenkins-host-key-verification-failed/15196114#15196114, this is caused due to the lack of the ~/.ssh/known_hosts entry for the github server (on my case below github.intuit.com…

What should I do in this case? I thought about copying the entry from another host to the server… (My problem is that I’m running Jenkins from a Docker Container)…

Thanks for any help!

I tried many times to get this to work…

Attached to the worker container and created a key

I added the public id to my Github profile

At this point, this solved the problem of cloning. Only through the container… However, from Jenkins it still fails…

Fails in the UI

It fails with the error below…

I’m suspecting something is wrong… The compose binary that I transferred is not executing properly…

bash-4.2# chmod +x /usr/local/bin/docker-compose
bash-4.2# docker-compose
bash-4.2# docker-compose --version
bash-4.2# docker-compose
bash-4.2# docker-compose
bash-4.2# docker-compose --version
bash-4.2# docker-compose up
bash-4.2#

Question

Should the Slave image eeacms/jenkins:centos-slave or the others also include the binary of docker-compose? What’s the intended way of using it?

[root@pppdc9prd8ok eea.docker.jenkins]# docker ps
