Automate Your Site Checks with Cron (and WPCron)
Want to monitor all your cron jobs on your WordPress site? You can do this, but it’s messy. Really messy.
#HealthCheck
I forgot to reconnect the #ups monitoring usb cable, so I received some alarms from my #healthcheck script (https://git.ichibi.eu/penguin86/selfhost-utils/src/branch/master/healthcheck), but the #server #booted happily. I didn't #reboot since some months and the last time it was completely turned off was in september, so I was a little worried, but it worked perfectly!
The Nextcloud pod as seen under the Podman containers menu in Cockpit.
In a termninal, I can run:
$ sudo podman healthcheck run nextcloud-app
to run the healthcheck on a single container, or run:
$ sudo podman ps
to see the health state for all running containers.
4) caddy:latest
The caddy image doesn't have any built-in healthcheck, and even `curl` is missing.
Luckily `wget` is available, and I use it to call Nextcloud's status page. This does check for more than the health of the caddy service itself.
Add the following in the [Container] section of the nextcloud-web.container:
...
HealthCmd=wget --quiet --spider --tries=1 https://cloud.example.com/status.php || exit 1
HealthStartPeriod=10s
HealthInterval=30s
HealthTimeout=5s
HealthRetries=5
Notify=healthy
...
3) nextcloud:fpm-alpine
This one wasn't obvious, but I was able to put something together, inspired by a closed github issue. The HealthCmd uses the built-in `occ status` command.
Add the following in the [Container] section of the nextcloud-app.container:
...
HealthCmd=php occ status 2>/dev/null | grep -e "installed: true" -e "maintenance: false" -e "needsDbUpgrade: false" | wc -l | [ "`cat`" = "3" ] || exit 1
HealthStartPeriod=20s
HealthInterval=60s
HealthTimeout=10s
HealthRetries=5
Notify=healthy
...
2) valkey/valkey:alpine
I've recently switched from redis to valkey, but they are compatible. I'll use the redis-cli tool to ping the service.
Add the following in the [Container] section of the nextcloud-redis.container:
...
HealthCmd=redis-cli ping || exit 1
HealthStartPeriod=10s
HealthInterval=30s
HealthTimeout=30s
HealthRetries=3
Notify=healthy
...
#podman #nextcloud #quadlets #healthcheck #redis #valkey

1) mariadb:10.11
This one was easy, since healthcheck is documented.
Add the following in the [Container] section of the nextcloud-db.container:
...
HealthCmd=healthcheck.sh --connect --innodb_initialized || exit 1
HealthStartPeriod=10s
HealthInterval=10s
HealthTimeout=5s
HealthRetries=3
Notify=healthy
...
I'm running a Nextcloud pod, based on quadlets. Now I want to add healthchecks to each container. At least it will look pretty in Cockpit...
In systemd unit files, the healthcheck is called a HealthCmd. Sometimes you're lucky and the corresponding Dockerfile has a healthcheck defined you can use, other times you have to make your own healthcheck.
I'm using 4 container images:
1) mariadb:10.11
2) valkey/valkey:alpine
3) nextcloud:fpm-alpine
4) caddy:latest
(The fifth container, a proxy server, mentioned in the repository below, is running on another host)

Как сделать livenessProbe для Kafka-консьюмеров и перестать перезапускать их вручную
Kafka-консьюмеры не всегда работают так стабильно, как хотелось бы. Иногда они просто зависают — без ошибок, без падений, но и без обработки сообщений. LivenessProbe в Kubernetes помогает автоматически перезапускать зависшие сервисы, но с Kafka-консьюмерами всё не так просто: стандартного решения для них нет. В этой статье разберём, как правильно реализовать livenessProbe для консьюмеров с помощью паттерна Heartbeat , чтобы не перезапускать их вручную.

Health checks in ASP.NET Core are used to check the health of the application. It is used to check the status of the application and its dependencies at regular intervals.
The app is considered alive and healthy if it can respond at the health endpoints.

Yes, I think this is possible.
For a completely DIY approach, use @termux which gives you a full Linux shell.
For a more polished setup I would look into @owntracks and I would cc @jpmens who might elaborate on same to see if it is flexible enough to do the needful.
Termux would need `cron` to work, I have not tried that myself, or maybe you do a while true sleep 600 style loop.
