I'm trying to use the --privileged tag on a self hosted runner but I keep getting an error stating that it's not allowed. I've run the same step on bitbucket's docker and it runs fine. To keep things basic, I'm currently using code cut and pasted from the support page detailing the use of runtime v3. The only difference I can see is that my runners keep insisting on downloading bitbucket-pipelines-docker-daemon v25.0.5 while on the hosted environment it appears to be running docker v28.5.1
My bitbucket-pipelines.yml is as follows:
options:
runtime:
cloud:
version: "3"
pipelines:
custom:
privileged-docker-run:
- step:
runtime:
cloud:
version: 3
image: atlassian/default-image:5
runs-on:
- 'self.hosted'
- 'linux'
services:
- docker
script:
- docker version
- docker info
- docker run --privileged alpine:3 sh -c "echo 20 > /proc/sys/vm/swappiness && cat /proc/sys/vm/swappiness"
