migrations package
This package handles the generation of the database schema in a format that can
be compiled into the boundary binary.
Organization
./generate
: contains the makefile, code, and templates needed to generate the schema info.
./postgres
: contains the versioned schema folders. The contents of these folders, except
for dev
should not be modified.
Usage
To regenerate the schema information into the format the boundary binary uses run
make migrations
or make gen
to recreate all generated code.
The content of the folders under ./postgres
are compiled into the
boundary binary and when the boundary database init
or boundary database migrate
commands are executed they are applied in order of their version.
The ./postgres/dev
directory contains schema files that are under development and
are not included in a release yet and so it is the only directory where additions and
modifications are allowed. When a boundary binary is built when this directory is not
empty a special flag is required to run the boundary database init
command to indicate
the user is aware that this is a development release and running this command can
result in a completely broken schema and dataloss.
When a new release is made the contents of the dev
directory are moved into a new
versioned directory.
