IPv6 setup fails because URL is not found about matrix-docker-ansible-deploy HOT 3 CLOSED

Thanks to d9598f0 (slightly fixed up in 4d91e8b), you can now easily pass additional Docker options via the playbook.

Example:

matrix_playbook_docker_installation_daemon_options_custom:
  default-address-pools: ...
  fixed-cidr-v6: ...

These _custom options will be merged with the default ones (matrix_playbook_docker_installation_daemon_options_auto) defined here:

from matrix-docker-ansible-deploy.

I've got the same issue when setting

devture_systemd_docker_base_ipv6_enabled: true

The relevant message is

could not find an available, non-overlapping IPv6 address pool among the defaults to assign to the network

Seems that you just have to enable dynamic ipv6 subnet allocation via default-address-pools.

from matrix-docker-ansible-deploy.

I added an IPv6 pool in default-address-pools and a fixed-cidr-v6 prefix. But I noticed these kept getting overridden.
To fix this, I added the following to my vars.yml:

matrix_playbook_docker_installation_enabled: false

Otherwise, the /etc/docker/daemon.json file kept getting overridden.

Now v6 works fine for the synapse container 😄
