Docker and CI/CD · Senior · Question 22 of 75

A Node app spawns headless Chrome and the container fills up with zombie processes. Why?

✓Correct answer: Node as PID 1 doesn't reap orphans; use an init like tini
2Docker limits each container to 16 processes
3Chrome can't run in containers without --privileged

Explanation

Orphaned grandchildren are re-parented to PID 1, which must wait() for them. --init, tini or shareProcessNamespace handles that.
