docker-network-tools

Docker network tools. support floating IP, Network namespace sync, OVS and linux bridge.

Concepts

This scripts are for docker network management script. docker's network is NAT based, but it can be used with just like openstack or something. yup, Float IP.. just DNAT/SNAT to specific container.

You can use docker with OVS(Open-V-Switch) and with Linux-bridge with low level setting. newer Docker can't setup with LXC option, so I need to setup docker with linux namespace.

• Why bash script?
  • because, It can run within even CoreOS. some Docker based OS doesn't have any support of python or something. so, I have to use bash.

Usages

• All scripts are requied root permission. because scripts are handling iptables, docker process and linux kernel namespace.

• Floating IP support

• Add : docker-floatip-add [FLOAT_IP_WITH_SUBNET] [CONTAINER_ID]

  • ex) docker-floatip-add 10.1.2.3/24 docker_name

• Delete : docker-floatip-del [FLAOT_IP_WITH_SUBNET]

  • ex) docker-floatip-del 10.1.2.3/24

• Restore : docker-floatip-restore (Restore whole configuration.)

  • ex) docker-floatip-restore

• Down/Clean up hole setting : docker-floatip-down

  • ex) docker-floatip-down

• Linux namespace sync support

  • docker-netns-sync : keep sync linux namespace with docker container.
  • docker-event-wait : this is compiled golang binary, which supports just wait until new docker's event. src is https://github.com/ziozzang/docker-base-dev-env/tree/master/utility/docker-event-wait

• OVS(openvswitch) support

• linux bridge support
