Accessing docker host from (jenkins) docker container

Question

I need to run docker commands from jenkins which is installed as a container on docker. My local setup is on an OSX and I use boot2docker to virtualize the docker machine.

Answer 1

I ran into exact same problem with my Jenkins docker plugin. Docker uses tls by default but docker plugin only supports http. What I did is disabling TLS verification on the docker machine. My docker machine is an Ubuntu so the docker conf file is under /etc/default/docker. Inside the conf file, you can disable TLS by adding

--tls=false 

in DOCKER_OPTS. Something like:

DOCKER_OPTS='-H tcp://0.0.0.0:2376 -H unix:///var/run/docker.sock --tls=false'
