FAQ

Q: webhook fails with error __nanosleep_time64: symbol not found

On Raspberry Pi, running alpine-3.12 fails with error:

$ docker run -it theohbrothers/docker-webhook:2.8.0-alpine-3.12
Error relocating /usr/local/bin/webhook: __nanosleep_time64: symbol not found

The solution is to use alpine-3.13 or later

$ docker run -it theohbrothers/docker-webhook:2.8.0-alpine-3.13

Q: ping fails with error ping: clock_gettime(MONOTONIC) failed

On Raspberry Pi, running ping on alpine-3.13 and above might fail with error:

$ docker run -it theohbrothers/docker-webhook:2.8.0-alpine-3.13
PING 1.1.1.1 (1.1.1.1): 56 data bytes
ping: clock_gettime(MONOTONIC) failed

The solution is to use --security-opt seccomp=unconfined option. See here

$ docker run -it --security-opt seccomp=unconfined theohbrothers/docker-webhook:2.8.0-alpine-3.13
