问题描述
我有以下简单的脚本，主要用于测试 https://github.com/docker/docker-py 是否能够在 bitbucket 容器内运行命令：
import docker
CLIENT = docker.DockerClient(base_url="unix://var/run/docker.sock")
for image in CLIENT.images.list():
print(image)
以下是我的相关管道阶段：
script:
- apt-get -y update
- apt-get install -y git-lfs
- apt-get install -y libgl1-mesa-glx
- pip install -r requirements/integration.txt
- docker images
- pytest -s -v tests/test_integration_dummy.py
但是我看到像这样奇怪的日志消息：
+ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
+ pytest -s -v tests/test_integration_dummy.py

=========================== short test summary info ============================
ERROR tests/test_integration_dummy.py - docker.errors.DockerException: Error ...
!!!!!!!!!!!!!!!!!!!! Interrupted: 1 error during collection !!!!!!!!!!!!!!!!!!!!
=============================== 1 error in 0.75s ===============================
Searching for test report files in directories named [test-results,failsafe-reports,test-reports,surefire-reports] down to a depth of 4
Finished scanning for test reports. Found 0 test report files.
Merged test suites,total number tests is 0,with 0 failures and 0 errors.
所以很明显容器内有 docker 那么为什么无法连接到它。
任何线索将不胜感激。
