ssl - adding ip with forwarding rules in google cloud -

can provide tutorial on how add additional ip instance via forwarding in google cloud?

the current documentation complicated , not helpful. not states command should executed , instruction vague.

i've been trying setup new instance, not understand on how setup forwarding of traffic on instance other instance. highly appreciate if shine light on topic.

thank you.

i understood question differently (compared other answer). understand need second public ip pointing instance has own public ip. if case, follow these steps:

1. let's start sdk, since mention:

   it not states command should executed , instruction vague

the commands executed in terminal once have downloaded , installed google cloud sdk. in linux/os x be:

    curl https://sdk.cloud.google.com | bash 

there's 3-step guide in link more information.

2. issue command:

   gcloud compute instances list 

to list of instances , zone belong to. take note of name , zone of instance need work with. notice region needed in commands below, first part of zone field. (for example: zone: us-central1-f, region us-central1)

3. create static public ip receive traffic want forward:

   gcloud compute addresses create name gcloud compute addresses create targ-ip-1 

where name again, of choice. prompt region (pick same region instance is). command return ip, let's say: w.x.y.z

4. you need create target-instance:

   gcloud compute target-instances create name --instance instance gcloud compute target-instances create targ-ins-1 --instance instance-1 

where name name of choice target instance. instance name of instance handling traffic 1 or more forwarding rules. prompt zone (pick same zone instance is).

you can create target-pools point several instances @ same time, instead of target instance.

5. create forwarding rule, using target instance , static public ip created:

   gcloud compute forwarding-rules create name --address address --target-instance target_instance --target-instance-zone target_instance_zone --ip-protocol ip_protocol --port-range [port | port-port] gcloud compute forwarding-rules create fwd-rule-1 --address w.x.y.z --target-instance targ-ins-1 --target-instance-zone us-central1-f --ip-protocol tcp --port-range 5678-5680 

where:

• name: name of choice forwarding rule
• address: ip address reserved in step 3
• target_instance: target instance name created in step 4
• target_instance_zone: zone target instance belongs to
• ip_protocol (optional): ip protocol rule serve. if left empty, tcp used. supported protocols are: ah, esp, sctp, tcp, udp.
• port (optional): if specified, packets addressed ports in specified range forwarded. if not specified, ports matched

you prompted select region rule belong to.

to verify rule, can list configured forwarding rules this:

gcloud compute forwarding-rules list 

you should start receiving traffic pointing new public ip, in instance chose.
