Following up on Need help dockerize an apt-cacher-ng service, one of the problem is, although my apt-cacher-ng service is up and running, but it is only listening to IPv6:
$ netstat -tanp | grep 3142
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp6 0 0 :::3142 :::* LISTEN -
Again, I'm following
Dockerize an apt-cacher-ng service
https://docs.docker.com/engine/examples/apt-cacher-ng/
Is something missing from that doc?
(The only thing I changed from the doc is to replace the "FROM" base from ubuntu
to debian:sid
)
