I have the below simple script which is basically to test whether https://github.com/docker/docker-py is able to run commands inside bitbucket containers:
import docker
CLIENT = docker.DockerClient(base_url="unix://var/run/docker.sock")
for image in CLIENT.images.list():
print(image)
And below is my relevant pipeline stage:
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
However i see strange log messages like so :
+ 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.
So it is quite clear that there is docker inside the container then why is not being able to connect to it .
Any clues would be greatly appreciated.
