Hi.
I'm trying to use docker_image to pull an image from my private repository
but I keep getting this error: "Get http://: http: no Host in request URL".
Here is what my task list currently looks like:
docker_login:
registry: our.docker.repo.com
username: foo
password: bar
- name: pull docker-jenkins image
docker_image:
name: "our.docker.repo.com/jenkins:stfs"
tag: "stfs"
...but I've tried all kinds of combinations of not specifying the tag in
the "name" attribute, only specifying it there, specifying the
"docker_host" attribute, specifying the "repository" attribute but I can't
seem to get things working and I have no idea what the problem is.
I actually just now tried to change this to pull the official
jenkinsci/jenkins image and I get the same error... so it doesn't seem to
be related to using private repositories.
Here is the error I'm getting after turning on verbose
output: https://gist.github.com/StFS/e275130e88c22233016282516a20b09a
I also tried turning on the "don't delete the temp files" and did the
"explode" / "execute" thing and added print statements here and there and
ended up finding out that the problem actually occurs inside the docker-py
libraray but then I gave up and decided that maybe I should try asking here
instead (I did try the IRC channel but got no answer).
Some "fun facts" I should mention:
- I'm using vagrant to test this
- I'm on Ubuntu using ansible 2.2.0.0
- The virtual machine being set up is CentOS 7
Also, I logged into the vagrant machine via SSH and ran the docker commands
corresponding to what I'm doing above (both 'docker login'/'docker pull
our.docker.repo.com/jenkins:stfs' as well as just 'docker pull
jenkinsci/jenkins' and they all worked fine.
Of course I've tried to google and I have found some hits for the literal
string "Get http://: http: no Host in request URL" but they all refer to
non-ansible things and I've been unable to figure out how to apply any
solutions mentioned there to my particular circumstance.
So... can anybody think of anything I can do here?
Kind regards, Stefan Freyr.
