Issue Summary
When running multiple Remote Agents on the same server using the same user, a race condition exists where multiple Docker Login tasks can overlap and the wrong credentials can be used.
This is reproducible on Data Center: (yes)
Steps to Reproduce
Setup:
- Remote Agent A and B are installed on one server
- Build TEST-A and TEST-B both use authenticated docker tasks
- TEST-A is assigned to agent A. The first task executes a docker login.
- A very short amount of time after TEST-A executes it's docker login, TEST-B executes a docker login using different credentials
Expected Results
TEST-A and TEST-B both use the appropriate credentials as defined in the web UI.
Actual Results
In limited scenarios where the docker login tasks are executed in a very short period of time the credentials may get overwritten before being referenced by the task, or when a task ends it performs a docker logout and removes any credentials from the system.
Task fails with invalid credentials error.
Workaround
There are currently two known workarounds:
- Deploy all remote agents on dedicated users (User A for Remote Agent A) when installing more than 1 agent per server.
- Deploy 1 remote agent per server.
