Docker-compose up fails on first time

[rickmak]

(user) got a problem when I run docker-compose -f docker-compose.yml up of skygear-server first time

p_1    | time="2016-09-26T04:17:23Z" level=error msg="Unable to begin transaction for schema migration: dial tcp 172.18.0.3:5432: getsockopt: connection refused" logger=skydb
app_1    | time="2016-09-26T04:17:23Z" level=error msg="Failed to start skygear: failed to open connection: skydb/pq: unable to connect to database because of a network error = dial tcp 172.18.0.3:5432: getsockopt: connection refused"

• Skygear Server Date/Version: 0.17.1
• Application Platform:
• Is this a regression?
• Attached logs, screenshots

Expected Results

First run will work.

Actual Results

Second run will work.

Steps to reproduce

This is not a regression.

There are a couple of solutions to this problem:

• change the docker image so that skygear-server will restart on fails
• introduce a delay before skygear-server is run
• skygear-server wait for longer before giving up
