Docker image / BusyBox version

[ddewaele]

We've centralized our prometheus / alertmanager config via a Spring Cloud Config (http) server.

We've extended the prom/prometheus image to fetch the config before starting prometheus.

We're having issues when we are retrieving the config through an Amazon Application Loader Balancer, where wget returns error getting response

This seems to be related to the following BusyBox issue, fixed in v1.27 https://bugs.busybox.net/show_bug.cgi?id=9471

I noticed that the Prometheus Dockerfile uses quay.io/prometheus/busybox:latest, a v1.26.2 version.

Here are the results of the wget call :

Prometheus v1.7.1

docker run -ti --rm prom/prometheus:1.7.1

Linux caea1378173d 4.9.41-moby #1 SMP Wed Sep 6 00:05:16 UTC 2017 x86_64 GNU/Linux
BusyBox v1.26.2 (2017-01-12 18:09:33 UTC) multi-call binary.
/ #  wget http://aws-app-loadbalancer/config/ixortalk.prometheus/dev/master/prometheus.yml
wget: error getting response

Using the latest busybox the wget works fine:

docker run -it --rm busybox:1.27

Linux cbbf44617185 4.9.41-moby #1 SMP Wed Sep 6 00:05:16 UTC 2017 x86_64 GNU/Linux
BusyBox v1.27.2 (2017-08-22 23:59:28 UTC) multi-call binary.

/ #  wget http://aws-app-loadbalancer/config/ixortalk.prometheus/dev/master/prometheus.yml
prometheus.yml       100% 

Are there any plans have prometheus use a more up-to-date version of BusyBox ?

[sdurrheimer]

I have triggered a new build of the quay.io/prometheus/busybox:latest which will then use the latest busybox version.

But this won't rebuild the prometheus 1.7.1 release on this updated image.

[ddewaele]

ok .... will prometheus:latest then pick up the new busybox version ?

[sdurrheimer]

No, prometheus:latest correspond to the latest stable release, which is 1.7.1 currently.

You will need to wait a 1.7.2 release or try the master tag.

[ddewaele]

You guys rock ! the wget works now ... will do some additional testing with prometheus itself.

So if all goes well the 1.7.2 release will contain BusyBox 1.27 ?

Is there a timeline yet ?

[ddewaele]

Also noticed that prometheus and alertmanager are using different busy box base images:

• Prometheus : quay.io/prometheus/busybox:latest
• AlertManager : prom/busybox:latest

Perhaps these should also be aligned ?

Yes it will but I don't know when a 1.7.2 will be released. Maybe @fabxc or @brancz have more informations about that.

Prometheus : quay.io/prometheus/busybox:latest
AlertManager : prom/busybox:latest

You're right, this should be aligned, but technically it is the same image, just pushed to two different repository.

[brancz]

I'm happy to cut a release if reasonable.

I'm closing it since the issue is outdated.
