inventory_hostname
When using a dynamic inventory inventory_hostname isn't guaranteed to be usable. We should use openshift.common.hostname which

openshift_node_dnsmasq - Remove strict-order option from dnsmasq
|
| |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| | |
strict-order forces dnsmasq to iterate through nameservers in order. If one of
the nameservers is down this will slow things down while dnsmasq waits for a
timeout. Also, this option prevents dnsmasq from querying other nameservers if
the first one returns a negative result. While I think it's odd to have a
nameserver that returns negative results for a query that another returns
positive results for this does seem to fix the issue in testing.

In 3.3 one of our services lays down a systemd drop-in for configuring
Docker networking to use lbr0. In 3.4, this has been changed but the
file must be cleaned up manually by us.
However, after removing the file docker requires a restart. This had big
implications particularly in containerized environments where upgrade is
a very fragile series of upgrading and service restarts.
To avoid double docker restarts, and thus double service restarts in
containerized environments, this change does the following:
- Skip restart during docker upgrade, if it is required. We will restart
on our own later.
- Skip containerized service restarts when we upgrade the services
themselves.
- Clean shutdown of all containerized services.
- Restart Docker. (always, previously this only happened if it needed an
upgrade)
- Ensure all containerized services are restarted.
- Restart rpm node services. (always)
- Mark node schedulable again.
At the end of this process, docker0 should be back on the system.

Fix rare failure to deploy new registry/router after upgrade.

Router/registry update and re-deploy was recently reordered to
immediately follow control plane upgrade, right before we proceed to
node upgrade.
In some situations (small or single host clusters) it appears possible
that the deployer pods are running when the node in question is
evacuated for upgrade. When the deployer pod dies the deployment is
failed and the router/registry continue running the old version, despite
the deployment config being updated correctly.
This change re-orderes the router/registry upgrade to follow node
upgrade. However for separate control plane upgrade, the router/registry
still occurs at the end. This is because router/registry seems like they
should logically be included in a control plane upgrade, and presumably
the user will not manually launch node upgrade so quickly as to trigger
an evac on the node in question.
Workaround for this problem when it does occur is simply to:
oc deploy docker-registry --latest

Set nameservers on DHCPv6 event

| | | | |
A dhcp6-change event may happen on nodes running dual stack
IPv4/IPv6 and DHCP, even if Openshift itself doesn't use IPv6.
/etc/resolv.conf needs be adjusted as well in this case.

Make it so that we don't relabel /etc/etcd/ (via `:z`) on every run.
Doing this causes systemd to fail accessing /etc/etcd/etcd.conf when
trying to run the systemd unit file on the next run. Convert it from
`:z` to `:ro` since we only need read-only access to the files.

Was getting a different failure here complaining that openshift was not
in the facts, as we had not loaded facts for the first master during
playbook run. However this check was used recently in
upgrade_control_plane and should be more reliable.

The `list.yml` playbooks are using cloud provider specific variables to find
the IPs of the VMs since 82449c6.
Those “cloud provider specific” variables are the ones provided by the dynamic
inventories.
But there was a problem when the `list.yml` playbooks are invoked from the
`launch.yml` ones because, in that case, the inventory is not coming from the
dynamic inventory scripts, but from the `add_host` done inside
`launch_instances.yml`.
Whereas the GCE and AWS `launch_instances.yml` were correctly adding in the
`add_host` the variables used by `list.yml`, libvirt and OpenStack were missing
that.

`systemctl show` would exit with RC=1 for non-existent services in v231.
This caused the Ansible systemd module to exit with a failure of running the
`systemctl show` command instead of exiting stating the service was not found.
This change catches both failures on either older or newer versions of systemd.
The change in systemd exit status could be resolved in systemd v232.
