I 've been working with dockers for almost a year, did a lot of task and when finally I thought of bringing docker to prod environment, I hit a major block. UDP and TCP traffic is not reaching my docker containers.
This issue is bit strange, on my Test environment I don’t see any packets getting drop but on the production servers where I 'm trying to run docker, it is dropping UDP as well as TCP packets. The docker version (1.8) and the host OS (OEL 7) is same in both the environments. All the packets are reaching to my host server but they don’t enter my containers, so no issue with the n/w dropping the packets.
Has it anything to do with the class of IP? My hosts on my lab setup has an ip range of 172.x.x.x while the production setup has 10.10.x.x. Has the netmask anything to do with this problem?
I 'm running out of options to check, any pointers to debug would be helpful here.
