Sync mode

As shown in the diagram below, User A and User B use the kubevpn sync command to sync the same service authors:

• User A: kubevpn sync deployment/authors --headers user=A --sync ~/code:/app/code
• User B: kubevpn sync deployment/authors --headers user=B --sync ~/code:/app/code

When the authors service in the cluster receives traffic:

• Traffic with user: A in the HTTP header will hit the sync service authors'.
• Traffic with user: B in the HTTP header will hit the sync service authors''.
• Unmatched traffic in the HTTP header will hit the original authors service in the cluster.

File synchronization is implemented using syncthing:

• The ~/code on user A's computer will be synchronized to the /app/code directory of the sync resource authors' in the cluster.
• The ~/code on user B's computer will be synchronized to the /app/code directory of the sync resource authors'' in the cluster.
