Deployment

Build the application

Use Kocha command line tool:

kocha build

Or use go build:

go build -o appname

These commands are generate a binary of Kocha app to $GOPATH/appname/appname.

Deploy the application

You can use any file transfer tool such as rsync in order to deploy the your application.

rsync -avz appname public targethost:/path/to/appdir/

Migration

In development environment, use kocha migrate command for migration.
You can do migration using the built your application in the same way.

For forward migration:

appname migrate up

For backward migration:

appname migrate down

Where appname is your application name.
Please see Migration for more details.

True All-In-One binary

A generated binary by kocha build (or go build) doesn't include static files. (Usually, static files are in public directory)
If you want to generate a binary which include static files, use the following command:

kocha build -a

Deployment of True All-in-One binary is very simple. You just transfer that binary to the server and restart it.
You don't have to transfer other files to server.

Graceful restart

Kocha app can be Graceful restart (aka Hot reload) if you are using kocha.Run.
Send SIGHUP signal to your Kocha app such as using kill -HUP command in order to do it.

Sequence:

1. App receive SIGHUP
2. Run a new app process and starts new requests acceptance
3. Wait the end of accepted requests in old app process
4. exit the old app process

In fact, kocha.Run is using github.com/naoina/miyabi in order to graceful stop/restart.
If you want to change the signals to graceful stop/restart, please see document of github.com/naoina/miyabi.
