Why to specify BUILD_HOST?

Question

When deploying to multiple nodes, shouldn't we build the project on each node? why specifying BUILD_HOST in config file?

Answer 1

The project is built only on the build node, not on each node. According to the documentation :

For build commands the following configuration variables must be set:

• APP : the name of your release which should be built
• BUILD_HOST : the host where to build the release
• BUILD_USER : the local user at build host
• BUILD_AT : the directory on build host where to build the release. must exist.

The built release is then copied to your local directory .deliver/releases and can then be delivered to your production servers by using one of the deploy commands.
