Pipelines runners frequently asked questions
Where do Pipelines store the generated caches/artifact?
Steps from the same pipeline can be scheduled on multiple runners that run on different hosts. So in order to share caches and artifacts between steps we upload them to the Atlassian infrastructure.
What IP address do I need to whitelist to get Runner to work?
Refer to the list of the IP addresses that you need to whitelist to get your runner connected with Pipeline behind your firewall.
It's also advisable to whitelist the following IPs here if there's an issue with your runner build.
How do I set up proxy for docker images?
With a self-hosted runner you can use a custom docker-in-docker service.

services:
docker:
image: docker:dind
environment:
HTTP_PROXY: "http://username:password@proxy2.domain.com"
HTTPS_PROXY: "http://username:password@proxy2.domain.com"See docker documentation for details.
How I can access files on the host from the build script?
Unfortunately it's not possible to access the local files with the docker runtime as by default Runners limit access to the host, else if you depend on files on particular machines there's no guarantee those files are on all machines runners are on.
As a workaround we can suggest accessing the files on the host with an SFTP client from the Runner's build by running the following command: sftp {user}@{host}:{remoteFileName} {localFileName}
How do I use an insecure Docker registry?
With a self-hosted runner you can use a custom docker-in-docker service.
Example of a Dockerfile:

# my-custom-dind-image
FROM docker:dind
