當我嘗試從我的容器內連接到一個端口到另一個容器中，我是不成功，並得到，泊塢窗 - 沒有到主機的路由
[email protected]:/opt/f5massupgrade# curl -v https://172.17.0.1:6379
* Rebuilt URL to: https://172.17.0.1:6379/
* Hostname was NOT found in DNS cache
* Trying 172.17.0.1...
* connect to 172.17.0.1 port 6379 failed: No route to host
* Failed to connect to 172.17.0.1 port 6379: No route to host
* Closing connection 0
從泊塢窗主機我成功，
[[email protected] ~]# curl -v https://172.17.0.1:6379/0
* About to connect() to 172.17.0.1 port 6379 (#0)
* Trying 172.17.0.1...
* Connected to 172.17.0.1 (172.17.0.1) port 6379 (#0)
* Initializing NSS with certpath: sql:/etc/pki/nssdb
* CAfile: /etc/pki/tls/certs/ca-bundle.crt
CApath: none
如果我檢查iptables的我可以看到這個問題，
[[email protected] ~]# iptables -S INPUT
-P INPUT ACCEPT
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -i docker0 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
所以我添加以下，這一切運作良好，
iptables -I INPUT 4 -i docker0 -j ACCEPT
我失去了一些東西？
[[email protected] ~]# docker version

感謝，
你是如何運行你的容器？使用內部IP地址，如果容器在同一個Docker網絡中，它們只能互相訪問。 –
是的，他們都在同一個網絡上。我公開了每個端口所需的端口。我沒有設置任何IP，因爲它們都通過docker0進行通信 – felix001
