记一次安装kolla遇到DockerException: Error while fetching server API version: Timeout value connect was Timeout的问题
2024-09-28 10:08:44
1)环境信息：
docker版本：17.09，当docker的版本是12.06时，也会报这个错误
[root@localhost ~]# docker --version
Docker version 17.09.1-ce, build 19e2cf6
[root@localhost ~]#
kolla版本：ocata版本
[root@localhost kolla]# git branch -a
* stable/ocata
remotes/origin/HEAD -> origin/master
remotes/origin/master
remotes/origin/stable/ocata
remotes/origin/stable/pike
remotes/origin/stable/queens
remotes/origin/stable/rocky
[root@localhost kolla]#
2)问题现象
在执行kolla-build -b centos keystone命令时，提示如下错误
[root@localhost kolla]# kolla-build -b centos keystone
INFO:kolla.image.build:Found the docker image folder at /usr/share/kolla/docker
INFO:kolla.image.build:Added image base to queue
INFO:kolla.image.build:Attempting to run task BuildTask(base) for the first time
INFO:kolla.image.build.base:Building
ERROR:kolla.image.build.base:Unknown docker error when building
Traceback (most recent call last):
File "/usr/lib/python2.7/site-packages/kolla/image/build.py", line 416, in builder
for response in self.dc.build(path=image.path,
File "/usr/lib/python2.7/site-packages/kolla/image/build.py", line 132, in dc
self._dc = docker.Client(version='auto', **docker_kwargs)
File "/usr/lib/python2.7/site-packages/docker/client.py", line 99, in __init__
self._version = self._retrieve_server_version()
File "/usr/lib/python2.7/site-packages/docker/client.py", line 124, in _retrieve_server_version
'Error while fetching server API version: {0}'.format(e)
DockerException: Error while fetching server API version: Timeout value connect was Timeout(connect=60, read=60, total=None), but it must be an int, float or None.
3)原因分析
由于requests==2.18.0 bug的问题，导致执行命令的时候，一直报错，把requests升到2.18.1版本就好了
[root@localhost ~]# pip list |grep request
requests 2.18.0
requestsexceptions 1.4.0
[root@localhost ~]# pip install requests==2.18.1

4)部署环境的pip列表清单
以后部署kolla ocata 版本的时候，遇到pip的版本问题，可以参考这个清单
