| - | | + | When we stop docker to manipulate iptables it will not add the masquerade rule to the docker0 bridge. We need this iptables rule to make docker build work again. So first we are going to add the iptables rule manually. Find out which subnet is connected to docker0 |
| + | |||
| + | ip a s docker0 | ||
| + | < | ||
| + | 11: docker0: < | ||
| + | link/ether 02: | ||
| + | inet 172.17.0.1/ | ||
| + | | ||
| + | inet6 fe80:: | ||
| + | | ||
| + | </ | ||
| + | In this case the subnet is 172.17.0.0/ | ||
| + | iptables -t nat -A POSTROUTING -s 172.17.0.0/ | ||
| + | |||
| + | Now we have the rule added. Make it persistent. First install iptables-persistent | ||
| + | apt install iptables-persistent | ||
| + | It will tell you it created rules in: / | ||
| + | Check the rules.v4 file for the masquerade rule | ||
