PiKVM exports some rudimentary metrics, but requires authentication to
scrape them. At the very least, this will provide alerting in case the
PiKVM systems go offline.
`updatecheck` is a little utility I wrote that queries Fedora Bodhi for
updates and sends an HTTP request when one is found. I am specifically
going to use it to trigger rebuilding the _gasket-driver_ RPM whenever
there is a new _kernel_ published.
Instead of allocating a volume for each individual Buildroot-based
project, I think it will be easier to reuse the same one for all of
them. It's not like we can really run more than one job at a time,
anyway.
Now that Headlamp supports PKCE, we can use the same OIDC client for it
as for the Kubneretes API server/`kubectl`. The only difference is the
callback redirect URL
The latest version of the _OpenId Connect Authentication Plugin_ for
Jenkins has several changes. Apparently, one of them is that it
defaults to using the `client_secret_basic` token authorization method,
instead of `client_secret_post` as it did previously.
At some point, Firefly III added an `ALLOW_WEBHOOKS` option. It's set
to `false` by default, but it didn't seem to have any affect on
_running_ webhooks, only visiting the webhooks configuraiton page. Now,
that seems to have changed, and the setting needs to be enabled in order
for the webhooks to run.
I'm not sure why `disableNameSuffixHash` was set on the ConfigMap
generator. It shouldn't be, so that Kustomize can ensure the Pod is
restarted when the contents of the ConfigMap change.
This network policy blocks all outbound communication except to the
designated internal services. This will help prevent any data
exfiltration in the unlikely event the Firefly were to be compromised.
Rust Desk is a remote assistance software solution. The open source
edition is sufficient for what I want to do with it, namely: help Mom
and Dad troubleshoot issues on their PCs. Mom is currently having
trouble with the Nextcloud sync client, so I need to be able to help her
with that.
Sometimes, Grafana gets pretty slow, especially when it's running on one
of the Raspberry Pi nodes. When this happens, the health check may take
longer than the default timeout of 1 second to respond. This then marks
the pod as unhealthy, even though it's still working.
The `k8s-reboot-coordinator` coordinates node reboots throughout the
cluster. It runs as a DaemonSet, watching for the presence of a
sentinel file, `/run/reboot-needed` on the node. When the file appears,
it acquires a lease, to ensure that only one node reboots at a time,
cordons and drains the node, and then triggers the reboot by running
a command on the host. After the node has rebooted, the daemon will
release the lock and uncordon the node.
The `policy` Kustomize project defines various cluster-wide security
policies. Initially, this includes a Validating Admission Policy that
prevents pods from using the host's network namespace.
The _updatebot_ has been running with an old configuration for a while,
so while it was correctly identifying updates to ZWaveJS UI and
Zigbee2MQTT, it was generating overrides for the incorrect OCI image
names.
