Wanted change

As per issue #133 (which is now closed - sorry for the duplicate), enable IRTT support in the docker image. @drizuid indicated this change was pretty easy.

Adding the Alpine packages irtt and perl-path-tiny allowed an IRTT probe to be created, and verified as working.

e.g. The following was done to verify this might work

Add to Probes

+ IRTT
binary = /usr/bin/irtt

++ IRTT4
ipversion = 4

++ IRTT6
ipversion = 6

Add an irtt.conf target

+ IRTT
menu = IRTT
title = IRTT

++ USWest
menu = US West
title = netperf-west.bufferbloat.net
host = /IRTT/USWest4 /IRTT/USWest6

++ USWest4
menu = US West4
title = netperf-west.bufferbloat.net (ipv4)
probe = IRTT4
host = netperf-west.bufferbloat.net

++ USWest6
menu = US West6
title = netperf-west.bufferbloat.net (ipv6)
probe = IRTT6
host = netperf-west.bufferbloat.net

Manually install the packages:

apk add --no-cache perl-path-tiny irtt

Verify the configuration is valid with:

/usr/sbin/smokeping --config=/etc/smokeping/config --check

Restart the services in the container with:

s6-svc -d /run/service/svc-smokeping
s6-svc -u /run/service/svc-smokeping
s6-svc -d /run/service/svc-apache
s6-svc -u /run/service/svc-apache

Reason for change

To allow IRTT probes

Proposed code change

Add irtt and perl-path-tiny to the dockerfile apk add command

can you give it a test please, LSPIPEPR/SMOKEPING:2.8.2-R2-PKG-63A18256-DEV-3687C2F2646F99AE0B7FC4421DF27480A25EC1C7-PR-162

Massively fast turnaround thank you.

I've used the lower case version of that tag and the container verifies as working for me. I checked:

• container runs
• a smokeping configuration check is successfully
• irtt executable is present

(The container is running on a x86_64 Flastcar VM with docker compose)

core@tan ~ $ docker ps
CONTAINER ID   IMAGE                                                                                          COMMAND   CREATED          STATUS          PORTS     NAMES
