ansible: git module is hanging

Question

I am using Ansible and I am having a hard time making the git module works. I have read several posts of people having the same problem, I looked at the ansible doc, well I tried almost everything. I found a clear tutorial that I followed until they use git but again I have a problem when I use my repository... :/ The git task just hangs... no error, it is just stuck!

Here is my host file:

[web] dev1 ansible_ssh_host=10.0.0.101 ansible_ssh_user=root 

This is a vagrant VM running on virtualbox on my computer.

I took the playbook from this tutorial and did all the steps until step 08: https://github.com/leucos/ansible-tuto/tree/master/step-08

I run it on my VM, it works fine, then I add one task "Deploy my code" to use my repository... but this task does not work. It is a private repository on bitbucket. Does it make a difference?

- hosts: web   tasks:      - name: Deploy our awesome application       action: git repo=https://github.com/leucos/ansible-tuto-demosite.git dest=/var/www/awesome-app       tags: deploy      - name: Deploy my code       action: git repo=https://[email protected]/YAmikep/djangotutorial.git dest=/var/www/my-app       tags: deploy 

There might be something with the user, or the user running ansible, or the keys, etc, but I tried back and forth for hours and I am even more confused now... I just do not know what to do to debug that now and find out what is wrong and what I am missing.

Thanks.

Answer 1

There are a couple of reasons why the git module might be hanging, but the most possible is that the git clone command is waiting for a confirmation if the host key should be added to your server's known hosts. To verify if this is the problem execute ansible with the flag: --verbose, so that it runs in verbose mode, this will give you more information about the error.

If you confirm that the known hosts is the problem, then you have two choices:

Solution 1:

To avoid this problem with the git module use the accept_hostkey parameter.

- name: ensure jquery repo is available   git: [email protected]:jquery/jquery.git version=master accept_hostkey=True 

---

Solution 2:

Use the ansible-sshknownhosts third-party module before using the core git module:

- name: ensure github is a known host   action: sshknownhosts host=github.com state=present   - name: ensure jquery repo is available   git: [email protected]:jquery/jquery.git version=master accept_hostkey=True 

Since the knownhosts is not a core ansible module, you will need to install it first, please refer to the github repo docs for more information hon how to install it.

---

another solution would be to disable ssh host key checking, but this has security implications, so unless you really know what you are doing it is best to avoid this.
