Quick docker Healthcheck question

[YouveGotMeowxy]

I'm adding a healthcheck to my compose, and this appears to work so far:

    healthcheck:
      test: ["CMD", "wget" ,"--no-verbose", "--tries=1", "--spider", "https://apprise.mydomain.com/status"]
      interval: 1m
      timeout: 3s

Now I'd just like to change the URL from the external FQDN to an internal one so it's not having to reach out to the net every minute. something like http://localhost/status but that isn't working, and I can't figure out which internal URL to use instead?

You need to provide more details about your environment.

[you]  ------------- * [ apprise - 192.168.0.100/eth0 & 72.124.12.11/eth1 ] * ------- [internet]

Access is now (based on example above

• Locally (not localhost) but http://192.168.0.100
• Internet http://72.124.12.11
  • If you have a DNS server, maybe you configured an A Record that reads apprise.mydomain.com and points to 72.124.12.11. This of course allows you to now visit http://apprise.mydomain.com

but if you want to access the site locally, you need to be locally on the same network/machine.

I hope that helps

I'm just running the apprise container and want to add in the healthcheck to the container.

I asked ChatGPT and it produced this:

Docker's built-in healthcheck mechanism is configured at container creation time—not something you can simply add to a container that's already running. In other words, if you decide later that you’d like a healthcheck, you’ll need to update your Dockerfile (or Docker Compose configuration) and then re-create the container.

I went on to say if you update the Docker file, the change can likely work by adding the following to it;

HEALTHCHECK --interval=30s --timeout=10s --start-period=5s --retries=3 \
  CMD curl --fail http://localhost/status || exit 1

If your using docker-compose.yml, then you can add the following:

version: '3.8'
services:
  your-service:
    image: your-image
    healthcheck:
      test: ["CMD", "curl", "--fail", "http://localhost/status"]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 5s

Did you figure this out; can i close this off?
