Summary

Symptom

You are running Bamboo behind a proxy, and Bamboo may not be able to connect to external applications such as an AWS, an EC2 instance, or an external JIRA instance.

Solution

You should be able to overcome these issues by either specifying your proxy settings to Bamboo as system properties when starting up Bamboo or by adding the following system properties with appropriate string values to the bamboo.sh or wrapper.conf file of your Bamboo installation:

  • http.proxyHost

  • http.proxyUser

  • http.proxyPassword

  • http.proxyDomain

Please refer to the instructions on Starting Bamboo for details on how to specify Bamboo system properties via the bamboo.sh or wrapper.conf files.
