podman can not remove pod with multiple containers as non root user #2577

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description

I run AWX containers into single pod to mimic docker compose. While I try removing pod, it fails with use having not permissions to do that. Reason being (discussed in IRC) that recursive killing of pods kills the pause container first, thus loosing namespace for the memcached container.

Steps to reproduce the issue:

run pod with containers:

- name: create awx_pod
  command: >
    podman pod create --name awx

- name: Activate postgres container
  command: >
    podman run -d --pod awx --name postgres
    -e POSTGRES_USER="{{ pg_username }}"
    -e POSTGRES_PASSWORD="{{ pg_password }}"
    -e POSTGRES_DB="{{ pg_database }}"
    -e PGDATA="/var/lib/postgresql/data/pgdata"
    "{{ postgresql_image }}"
  register: postgres_container_activate

- name: Activate rabbitmq container
  command: >
    podman run -d --pod awx --name rabbitmq
    -e RABBITMQ_DEFAULT_VHOST="{{ rabbitmq_default_vhost }}"
    -e RABBITMQ_ERLANG_COOKIE="{{ rabbitmq_erlang_cookie }}"
    -e RABBITMQ_DEFAULT_USER="{{ rabbitmq_default_username }}"
    -e RABBITMQ_DEFAULT_PASS="{{ rabbitmq_default_password }}"
    "{{ rabbitmq_image }}"
  register: rabbitmq_container_activate

- name: Activate memcached container
  command: podman run -d --pod awx --name memcached memcached:alpine


- name: Activate AWX Web Container
  tags: test
  command: >
    podman run -d --pod awx --name awx_web
    -u root
    --hostname "{{ awx_web_hostname }}"
    -e http_proxy="{{ http_proxy | default('') }}"
    -e https_proxy="{{ https_proxy | default('') }}"
    -e no_proxy="{{ no_proxy | default('') }}"
    -e SECRET_KEY="{{ secret_key }}"
    -e DATABASE_NAME="{{ pg_database }}"
    -e DATABASE_USER="{{ pg_username }}"
    -e DATABASE_PASSWORD="{{ pg_password }}"
    -e DATABASE_PORT="{{ pg_port }}"
    -e DATABASE_HOST="{{ pg_hostname_actual }}"
    -e RABBITMQ_USER="{{ rabbitmq_default_username }}"
    -e RABBITMQ_PASSWORD="{{ rabbitmq_default_password }}"
    -e RABBITMQ_HOST="rabbitmq"
    -e RABBITMQ_PORT="{{ rabbitmq_port }}"
    -e RABBITMQ_VHOST="{{ rabbitmq_default_vhost }}"
    -e MEMCACHED_HOST="memcached"
    -e MEMCACHED_PORT="11211"
    -e AWX_ADMIN_USER="{{ admin_user|default('admin') }}"
    -e AWX_ADMIN_PASSWORD="{{ admin_password|default('password') }}"
    ansible/awx_web
  register: awx_web_container

- name: Activate AWX Task Container
  command: >
    podman run -d --pod awx --name awx_task
    -u root
    --hostname "{{ awx_task_hostname }}"
    -e http_proxy="{{ http_proxy | default('') }}"
    -e https_proxy="{{ https_proxy | default('') }}"
    -e no_proxy="{{ no_proxy | default('') }}"
    -e SECRET_KEY="{{ secret_key }}"
    -e DATABASE_NAME="{{ pg_database }}"
    -e DATABASE_USER="{{ pg_username }}"
    -e DATABASE_PASSWORD="{{ pg_password }}"
    -e DATABASE_HOST="{{ pg_hostname_actual }}"
    -e DATABASE_PORT="{{ pg_port }}"
    -e RABBITMQ_USER="{{ rabbitmq_default_username }}"
    -e RABBITMQ_PASSWORD="{{ rabbitmq_default_password }}"
    -e RABBITMQ_HOST="rabbitmq"
    -e RABBITMQ_PORT="{{ rabbitmq_port }}"
    -e RABBITMQ_VHOST="{{ rabbitmq_default_vhost }}"
    -e MEMCACHED_HOST="memcached"
    -e MEMCACHED_PORT="11211"
    -e AWX_ADMIN_USER="{{ admin_user|default('admin') }}"
    -e AWX_ADMIN_PASSWORD="{{ admin_password|default('password') }}"

I run the ansible as user, the same could be made pasting commands to command line
after pod is up, do podman pod rm awx

Dockerfile for the that "official" memcached image here: https://github.com/docker-library/memcached/blob/24ecf1cbeb76244031036eed161bb8bd00c99085/alpine/Dockerfile

This has something to do with setting the user.

join the user namespace where the pod is running, so that we can both manage the storage and correctly send the kill signal to a process which is not running as root in the namespace. Closes: containers#2577 Signed-off-by: Giuseppe Scrivano <[email protected]>
