Sep 28, 2017 · In our last post, we saw iptables basics, where we learned about how iptables works, what are the policies, and how to configure iptables policies.. While working on iptables, if you get confused about policies and you need to start afresh then you need to reset iptables to default settings. One might suggest that since we didn’t use the ‘-p’ flag docker didn’t know to make a rule in iptables. While that seems to be a possible fix it really isn’t. Starting the container with a port mapping yields the same result.

参考docker官方论坛的原贴。 故障原因是Docker用iptables初始化NAT网络，而Debian buster使用 nftables 而不是 iptables，导致dockerd不能正常完成NAT初始化，出错退出。 处理方法是调用update-alternatives强制Debian用iptables而不是nftables。 Jan 26, 2020 · If it is a DNS resolver problem, here is the solution: First thing to check is run cat /etc/resolv.conf in the docker container.If it has an invalid DNS server, such as nameserver 127.0.x.x, then the container will not be able to resolve the domain names into ip addresses, so ping google.com will fail.

The problem with iptables is more serious. ClearOS, when it restarts the firewall wipes iptables and it does not recreate the docker container rules. If iptables is turned on in docker, docker containers will do that only if restarted and this is not optimal. During development if you delete the DOCKER chain or the iptables rules get dropped (e.g. by a restart of firewalld) Docker will start logging iptables errors such as “failed programming external connectivity … iptables: No chain/target/match by that name”. To resolve simply restart Docker and the correct iptables rules will be created.
