This is a template for deploying golang binaries apps in CF. The template includes:

1. Local docker develpment
2. Connection tutorial to a mysql database
3. Bindata/Gomigrate to bundle DB migrations directly to the binary

The following assumes you have a working, recent version of Go installed, and you have a properly set-up Go workspace. Working on osx will require crosscompile. In a nutshell:

• Install go (tested with 1.5.x)
• Install docker for local development system
• Registered to public or selfhosted CF service

To start, given a working GOPATH , execute

go get github.com/karampok/gocf
go get -u github.com/jteeuwen/go-bindata/...
go get github.com/tools/godep
make localpush

The make localpush simply

• Binds the static data needed for db migration using go-bindata
• Creates the binary ./bin/gocf (note crosscompile on osx)
• Starts a MariaDB docker container

docker run -d --name mariadb --env-file ./mariadb.env  -p 3306:3306/tcp mariadb

• Starts our app in specific cf container

docker run -v ./gocf/bin:/opt/bin  --env-file ./env.list -p 4000:4000  --link mariadb:mariadb  -it cloudfoundry/cflinuxfs2 /opt/bin/gocf

Review the logs directly from the container.

Visit localhost:4000 in the browser.

Connect to the database by executing make db-client

Log in

cf login -a https://api.lyra-836.appcloud.swisscom.com

Create up a mysql Service.

cf create-service mariadb small mysql

Push the app. The manifest assumes you called your MariaDB instance 'mysql'.

make push

The make push simply

1. Binds the static data needed for migration using go-bindata
2. Creates the binary ./bin/gocf (note crosscompile on osx)
3. Pushes the app by executing cf push -c './gocf' -b https://github.com/cloudfoundry/binary-buildpack.git

Review the logs by executing cf logs --recent kka-gocf

Visit kka-gocf.scapp.io in the browser.

Connect to the database for debugging using connector plugin

cf service-connector 3306 <serviceIP>:3306  &
mysql -h 127.0.0.1 -u <user> -p  <pass>
