Bug 589150 – app-containers/docker: add iptables USE flag

• Status: RESOLVED INVALID
• Product: Gentoo Linux

[Description Daniel Maxime 2016-07-19 13:17:10 UTC]

This is an ebuild forked from the last version, adding "iptables" USE flag. Docker can works without iptables and (for me), I only use nftables.

This ebuild makes iptables dependancy optional.
Note: you need to add "--iptables=false --ip-masq=false" to dockerd options to make it run of course (if iptables binary is not found)

Reproducible: Always

If Docker uses or detects iptables during the build process this
patch is correct.

If not, the patch should just be an addition to pkg_postinst something
like:

if ! has_version 'net-firewall/iptables'; then
	elog "You may want to install iptables for blah blah functionality"
fi

Docker is not working without /sbin/iptables for me. I had to create a symlink for /sbin/iptables -> /sbin/xtables-legacy-multi by hand so that docker daemon would start.

I looked into this, and in the current versions of docker, iptables is a
hard requirement, so I can't make it optional.
