Ping not working in neither docker nor k3s

[heathcliff26]

Describe the bug

When running gatus from inside k3s or in plain docker, all attempts to monitor nodes via ping fail, despite the being reachable. I have verified that the nodes can be pinged from the gatus host.

What do you see?

When adding endpoint with ping, status check always fails, regardless of node status.

What do you expect to see?

Ping should succeed if the endpoint is reachable.

List the steps that must be taken to reproduce this issue

1. Create config.yaml with the following content:

endpoints:
  - name: router
    group: test
    url: "icmp://example.com"
    interval: 1m
    conditions:
      - "[CONNECTED] == true"
  - name: router-ipv4
    group: test
    url: "icmp://192.168.0.1"
    interval: 1m
    conditions:
      - "[CONNECTED] == true"

2. Start gatus with:

podman run -p 8080:8080 -v ./config.yaml:/config/config.yaml --name gatus -d  docker.io/twinproduction/gatus:v5.10.0

Version

v5.10.0

Can you try setting endpoints[].client.network to ip4?

endpoints:
  - name: router
    #...
    client:
      network: ip4

[heathcliff26]

I did, this does not seem to change anything.

[heathcliff26]

I don't know if you meant ip4 as written or ipv4, but i tried both:

endpoints:
  - name: router
    group: test
    url: "icmp://example.com"
    client:
      network: ipv4
    interval: 1m
    conditions:
      - "[CONNECTED] == true"

[TwiN]

I meant ip4, but no worries.

In that case, I reckon the problem has to have something to do with privilege magic.
I'm going to close this as a duplicate of #697
