Communicate with other workloads ¶
This guide shows you how to communicate with other workloads inside the same environment or cluster via service discovery.
Prerequisites ¶
- Your workload has configured policies for outbound traffic to the target workload
- The target workload has configured policies for inbound traffic from your workload
Identify the target address ¶
To identity the address of the workload we are communicating with, we need to know its name and what namespace its running in.
Target exists in the same namespace ¶
If the workload you are calling is in the same namespace, you can reach it by calling its name directly using HTTP like so:
Plaintext
http://<name>Target exists in another namespace ¶
If the workload is running in another team's namespace, you need to specify the namespace as well:
Plaintext
http://<name>.<namespace>Call the address ¶
Call the workload through its internal address using HTTP from your own workload:
http
GET /resource HTTP/1.1
Host: <name>.<namespace>
