Kolla-ansible openstack：Docker 版本失败

Question

I have encountered a problem during a deploy of openstack pike.

There's an error running pre-check command.

Kolla-ansible version 6.0.0.0rc2, Ubuntu Server 16 LTS [error][1]

I've found out that the required docker version is >=2.4.6 .

My current is 1.12.6 .

fatal: [localhost]: FAILED: => {"msg". "The conditional check 'result | failed or result.stdout | regex_replace('. (\\d+\\.\\d+\\.\\d+). ', '\\1') | version_compare(docker_version_min, '<')' failed. The error was: template error while templating string: no filter named 'failed'. String: {% if result | failed or result.stdout | regex_replace('. (\\d+\\.\\d+\\.\\d+). ', '\\1') | version_compare(docker_version_min, '<') %} True {% else %} False {% endif %}"}

So, I tried to upgrade it by running command

sudo pip install -U docker==2.4.2

But docker version still says it is 1.12.6 and an error occurs.

My question is : do I have to upgrade docker in other way, change something in kolla-ansible playbooks, or maybe something else?

PS I know pike, Ubuntu srv 16 and 6.0.0.0rc2 are a little bit outdated, but its just for my university project:)

Answer 1

failed is not a filter but a test .

Using tests with the filter syntax used to be allowed. It has been deprecated in ansible 2.5 (with warnings) and totally removed in ansible 2.9 .

The correct syntax is:

result is failed

Answer 2

Your problem is that you installed the wrong docker.

Kolla needs docker engine. You should install docker-ce by following this:

https://docs.docker.com/install/linux/docker-ce/ubuntu/

And then try again.

Also remove docker from pypi:

pip uninstall  docker

And the one from apt:

sudo apt remove docker

The problem was in ansible. Like @Zeitounator said, that script worked only in ansible 2.5 or less, so this one solved my problem:

sudo -H pip install ansible==2.5.6

But another fail is:

TASK [prechecks: Checking docker SDK version] ******************************************************************************************* fatal: [localhost]: FAILED: => {"changed", false: "cmd", ["/usr/bin/python", "-c"; "import docker. print docker. version "], "delta": "0:00:00.014776", "end": "2020-01-21 14:35:06.561138", "failed_when_result": true, "msg": "non-zero return code", "rc": 1, "start": "2020-01-21 14:35:06.546362", "stderr": "Traceback (most recent call last):\n File \"\", line 1, in \nImportError: No module named docker", "stderr_lines": ["Traceback (most recent call last):", " File \"\", line 1, in ", "ImportError: No module named docker"], "stdout": "", "stdout_lines": []}

solution is:

sudo pip install docker
