Go by Example

Content, toolchain, and web server for Go by Example.

Overview

The Go by Example site is built by extracting code & comments from source files in examples and rendering that data via the site templates. The programs implementing this build process are in tools.

The build process produces a directory of static files - public - suitable for serving by any modern HTTP server. We include a lightweight Go server in server.go.

Building

To build the site you'll need Go and Python installed. Run:

$ go get github.com/russross/blackfriday
$ tools/build
$ open public/index.html

To build continuously in a loop:

$ tools/build-loop

Local Deploy

Ro run and view the site locally:

$ mkdir -p $GOPATH/src/github.com/mmcgrana
$ cd $GOPATH/src/github.com/mmcgrana
$ git clone git@github.com:mmcgrana/gobyexample.git
$ cd gobyexample
$ go get
$ PORT=5000 CANONICAL_HOST=127.0.0.1 FORCE_HTTPS=0 gobyexample
$ open http://127.0.0.1:5000/

Heroku Deploy

To setup the site on Heroku:

$ export DEPLOY=$USER
$ export APP=gobyexample-$USER
$ heroku create $APP -r $DEPLOY
$ heroku config:add -a $APP
    BUILDPACK_URL=https://github.com/mmcgrana/buildpack-go.git
    CANONICAL_HOST=$APP.herokuapp.com \
    FORCE_HTTPS=1 \
    AUTH=go:byexample
$ heroku labs:enable dot-profile-d -a $APP
$ git push $DEPLOY master
$ heroku open -a $APP

Add a domain + SSL:

$ heroku domains:add $DOMAIN
$ heroku addons:add ssl -r $DEPLOY
# order ssl cert for domain
$ cat > /tmp/server.key
$ cat > /tmp/server.crt.orig
$ curl https://knowledge.rapidssl.com/library/VERISIGN/ALL_OTHER/RapidSSL%20Intermediate/RapidSSL_CA_bundle.pem > /tmp/rapidssl_bundle.pem
$ cat /tmp/server.crt.orig /tmp/rapidssl_bundle.pem > /tmp/server.crt
$ heroku certs:add /tmp/server.crt /tmp/server.key -r $DEPLOY
# add ALIAS record from domain to ssl endpoint dns
$ heroku config:add CANONICAL_HOST=$DOMAIN -r $DEPLOY
$ heroku open -r $DEPLOY
