[Chris Liles (christopherliles)]

A simple workaround is to add 'uwsgi' to barbican_api_packages_append and rebuild.

[Jeffrey Zhang (jeffrey4l)]

This is a bug need to be fix.

[Jeffrey Zhang (jeffrey4l)]

the uwsgi is installed. I tested this in master, it works.

[Christian Berendt (berendt)]

Works on master, closing as invalid.

[Magnus Lööf (magnus-loof)]

I am on Kolla 3.0.2, binary centos release.

If I run:

$ docker run --rm -ti kolla/centos-binary-barbican-api:3.0.2 /bin/bash
()[barbican@61a7fb825779 /]$ yum list installed | grep uwsgi

uwsgi is not installed, and it exibits the same error as above.

[Magnus Lööf (magnus-loof)]

And I see now in https://github.com/openstack/kolla/blob/master/docker/barbican/barbican-base/Dockerfile.j2 it is installed by pip.

But:

$ docker run --rm -ti kolla/centos-binary-barbican-api:3.0.2 /bin/bash
()[barbican@61a7fb825779 /]$ pip freeze | grep uwsgi

It is not installed.

[Magnus Lööf (magnus-loof)]

[Jeffrey Zhang (jeffrey4l)]

@magnus-loof, could u fix the newton branch?

[Magnus Lööf (magnus-loof)]

Some more investigation into this:

in docker/barbican/barbican-api/Dockerfile.js one can see that for ubuntu, the `package uwsgi-plugin-python` is installed in addition to `barbican-api`. For centos, the only package that is installed is `openstack-barbican-api`

Conclusion: `uwsgi-plugin-python` should be installed for Centos as well.

pip is only used to install uwsgi if it is built from source - as can be seen in barbican-base/Dockerfile.js - and this problem is related to binary release.

[Magnus Lööf (magnus-loof)]

I have examined the source code for master, as well as building `kolla/centos-binary-barbican-api` from master.

The problem with uwsgi in binary centos containers exists even in master.

Metadata for this issue seems incorrect.

Suggest changing

Affects Pike -> Affects Newton

Importance -> High for Ocata Release

Milestone -> Ocata 4.0.1 for Ocata Release

[Yuvaraja Mariappan (ymariappan)]

Hi,

where can i find the docker image for 4.0.1 release?
