Dependencies Installation
Scalingo installs the dependencies Go application using Go Modules.
Private Dependencies
Here is how to use a dependency in a private repository for your application.
The platform looks for environment variables that follow the following pattern:
GO_GIT_CRED__<PROTOCOL>__<HOSTNAME>
. Any periods (.
) in the HOSTNAME
must
be replaces with double underscores (__
).
The value of a matching var will be used as the username. If the value contains
a “:”, the value will be split on the “:” and the left side will be used as the
username and the right side used as the password. When no password is present,
x-oauth-basic
is used.
The following example will cause git to use the FakePersonalAccessTokenHere
as
the username when authenticating to github.com
via https
:
$ scalingo env-set GO_GIT_CRED__HTTPS__GITHUB__COM=FakePersoalAccessTokenHere
Defining a Procfile
web: <base package name>
Example if your package is github.com/user/example
:
web: example
Pre/Post Compile Hooks
If the file bin/go-pre-compile
exists and is executable, it will be executed before compilation.
Likewise, if the file bin/go-post-compile
exists and is executable, it will be executed after the compilation.
Because the buildpack installs compiled executables to bin
, the
go-post-compile
hook can be written in Go if it’s installed by the specified
<packagespec>
.
