@jessesimpson36 @npepinpe since camunda/camunda#13706 we don't have curl available in the zeebe dist anymore, as also there is no wget I went for a plain tcp check as health indicator for now 9e4152a

stable branches of this repo are not affected as they have no healtcheck :D

Do you see any better alternatives?

will merge for now to unblock the alpha release but let's follow-up on this

I've never seen this :> operator, but if the healthcheck works, then I have no issues! I mean, unless we're on an image that has bash compiled without support for network redirections ( the feature that /dev/tcp/host/port uses).

Also, I may have backported healthchecks to the stable branches. 😅

Also, I may have backported healthchecks to the stable branches. 😅

At least on stable/8.2 there are no health checks, now I checked 8.1 an there they are 😅 but 8.1 still has curl with the current patch, will fail next time we update then ^^

[jessesimpson36]

That's so strange. there should be healthchecks on all of them. Sometimes github does some merge-conflict resolution, and I'm wondering if the healthcheck change didn't make it. I'd like to add the healthchecks back in to each stable branch (8.1 and 8.2).

A minor concern I have is that some components are looking to switch to using alpine, which I think might break the :> /dev/tcp redirection

I'll try to get to this soon, but not when I have as many tickets as I'm currently dealing with.
