Docker Cloud - sleep necessary #12

Open revett opened 8 years ago

revett commented 8 years ago

Context

Just switched to running our Go apps as a static binary in a container based off sillelien/base-alpine.
Apps are running in containers on Docker Cloud (Ubuntu 14.04 nodes).
Problem
When one of our services starts, it attempts to connect to a RDS instance.
This was timing out.
Solution
Add a 20 second wait before trying to connect.
Logs
