Estou tentando configurar um aplicativo baseado em docker em um servidor virtual que executa o Ubuntu. O aplicativo deve funcionar com o IPv6. Não há problema, eu tenho uma rede / 64 do meu provedor de servidor, ele está funcionando bem até que eu inicie a rede docker habilitada para IPv6.
Quando a rede está em execução, meu servidor ainda pode ser acessado via IPv6 por fora, mas não consigo me conectar à Internet via IPv6 por dentro - obviamente há um problema de roteamento.
Descobri que o problema é a docker0 bridge padrão com seu endereço fe80::1 . Infelizmente, o gateway padrão (atribuído pelo meu provedor de servidor) também está no endereço fe80::1 , então, assim que a ponte estiver on-line, nada será roteado para a Internet.
Eu tenho tentado a tarde inteira para fazer o Docker usar um endereço IPv6 diferente para a ponte docker0 (que eu acho que deve resolver o meu problema), mas sem sorte. Existe uma opção --bip em dockerd , mas infelizmente só funciona com IPv4 e não há --bip-v6 . Eu também tentei a opção --fixed-cidr-v6 com outra sub-rede, mas isso só adicionou um endereço adicional à ponte sem remover fe80::1 .
Estou faltando alguma coisa? Existe uma maneira de usar outro endereço IPv6 para a interface de ponte? Ou talvez uma solução completamente diferente para o meu problema?
Esta é a minha tabela de roteamento IPv6:
