To support creating multiple docker bridges multiple kind job runs

[rajnkamr]

Describe what you are trying to solve

Currently a single docker bridge is created for each kind CI job, for multiple egress CI jobs running on a single kind test bed, we need to create multiple docker bridges catering to each kind job.

Describe the solution you have in mind

For supporting multiple egress tests on same kind test beds running in parallel we need to create multiple docker bridges like below

br-9bb19d1.11@br-9bb19d1d4e07: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
br-9bb19d1.12@br-9bb19d1d4e07: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
br-9bb19d1d4e07: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default 
    link/ether 02:42:a0:48:de:ad brd ff:ff:ff:ff:ff:ff

br-9bb19d1.11@br-9bb19d1d4e0x: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
br-9bb19d1.12@br-9bb19d1d4e0x: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
br-9bb19d1d4e0x: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default 
    link/ether 02:42:a0:48:de:ad brd ff:ff:ff:ff:ff:ff

I don't quite get the goal and the approach. What do you mean by "multiple docker bridges"? I see only one bridge in the output under "Describe the solution you have in mind".

And if you actually mean multiple clusters on single bridge, can multiple clusters just share the same vlan interface? I don't see why there must be one interface for each job.

Edited with multiple bridges( Had added one bridge as a sample ). Multiple jobs needs to run independent of each other, Meant in case of multiple clusters, for this reason we need multiple docker bridges as the bridges needs to be created with each new kind egress job run and will be cleaned up after job is ended/terminated, hence each job need to create/delete their own docker network.
