Step 'Wait for port 22 to be ready' stucked

[xunleii]

Hello,

I'm trying to test symplegma and I'm stucked at the first step : 'Wait for port 22 to be ready'.
Of course, if I try manually nc HOST PORT, I can find the string 'OpenSSH' and, if I comment this part, it works.

How to solve this problem ?

Environment:

• Ansible version: 2.7.8
• Provider: Scaleway
• OS: Ubuntu Bionic

Hi,

Thanks for trying it out.

That's weird, I only tested it on CentOS and CoreOS, I can try tomorrow on ubuntu. Do you have any debug log from ansible ?

[xunleii]

I'll try it now in debug mode and I'll join you the result :)

[xunleii]

Sorry for my response time, I would try something before writing my response :)

After testing with -vvv (and a lot of patience...) I found one problem: wrong ansible_python_interpreter value ... I've changed python with python3, but not /opt (for CoreOS I think) with /usr.

But this step still stucked and here is the debug logs :

Thanks for your help :)

NB: I've another problem with pip3 install.... but I'll write you an issue tomorrow about that

[ArchiFleKs]

The thing is that the role os_bootstrap should not be necessary if you already have python-dev and pip install.

I'll try quickly with ubuntu on AWS.

The bootstrap role installs python and pip for coreos in a standalone folder.

[ArchiFleKs]

Could you try setting bootstrap_python: false in group_vars

[xunleii]

After testing, python3 is installed by default, but not pip3 (I don't know where it used).
Also, if I skip python bootstrapping, it try to uninstall docker which is not installed by default.

I think OS Bootstrapping must be allowed only on CoreOS, avoid theses errors.

What do you think about that ?

[ArchiFleKs]

I've been trying to install on Ubuntu. There are a couple of error i'm fixing and will release today. It is mostly what you said:

• bootstrapping python must be done only for CoreOS, so bootstrap_python should be set to false in your case.
• python-dev and python-pip or python3-dev and python3-pip should be install for ansible.
• etcdctl is missing for non CoreOS OS by default, i'll add it also
• runc is missing also on ubuntu, I will add it to the containerd playbook
• bin_dir should be set to /usr/local/bin in non CoreOS os as it is in PATH by default and avoid error.
• docker.service masking should be allowed to fail in case it does not exist.

Thank you so much :)

[xunleii]

New version works well we Ubuntu ... thanks
