History

Julia Kreger 43e1af7ef0 Introduce longer deployment wait with multi-node testing The nature of multi-host interactions and testing can be extremely racey. Since IPA can offer SSH, the wait step can be short circuited resulting in us not waiting long enough. As such, introducing a longer wait _and_ re-check of SSH connectivity. While this does not completely fix the underlying race, it is intended to help the test be more reliable in CI.

bifrost-prepare-for-test-dynamic

Removes and re-adds the nodes to the SSH known_hosts file when the variable ipv4_address is defined.

Requirements

Role Variables

ipv4_address: The host IPv4 address defined on each host to perform the action to.

node_ssh_pause: The amount of time, defaulted to 4 seconds, to pause before attempting to connect to the node. This is useful if the test image has a tendency to have networking restart after sshd has started.

wait_timeout: The number of seconds to wait for SSH connectivity to the test machine to be established before proceeding.

Dependencies

As this role is purely for testing, dependencies are not hard coded into the role. The role expects to be executed after bifrost-deploy-nodes-dynamic where a node ipv4_address is defined on the host level.

Example Playbook

hosts: baremetal connection: local name: "Adds and removes a .ssh/known_hosts entry" become: no gather_facts: no roles:
