Can't run awx on ipv6 only host

[ruben-herold]

hi,

I ask already in #504 if you have an installation method without containers. Now I have test an installation on an testhost.

Unfortunately our complete network is ipv6 only and uses nat64 for ipv4 connectivity. After running your installation I have some docker container running and can access the frontend via http.

But If I try to exec some jobs or get connectivity to some external hosts it failes. Cause it don't use the host dns servers configured on host (they are doing DNS64) / or try to connect via ipv4 and nat. But the host server has no ipv4 enabled, cause here is no ipv4.

How can I install it with native manual configured ipv6 addresses and custom dns servers for each container? Sorry ipv4 is dead...

Hi,

found a solution, seems it is a docker problem:

1. you must activate ipv6 in docker (default off)

2. you must give the network a fixed-cidr-v6 (Link local only don'T start...) see:
   17.04 / 17.05: The disappearance of the link-local & loopback ipv6 addresses moby/moby#33099

3. configure nat / MASQUERADE on host for ipv6.

you can find information about it in :
https://docs.docker.com/engine/userguide/networking/default_network/ipv6/

You could also use routeable ip space but I'm not shure that the containers have propper secuirty settings for that...
