lift-web-deploy

Simple Ansible playbook to deploy liftweb applications on Ubuntu server 13.

Manage VM

VBoxManage controlvm "ubuntu server" poweroff; VBoxManage snapshot "ubuntu server" restore "initial-snapshot" && VBoxManage startvm "ubuntu server"

VM must be configured in virtualbox to have 2 network interfaces, one in NATm the other in Host Only. Set a static ip address to Host Only interface:

/etc/network/interfaces

The loopback network interface

auto lo iface lo inet loopback

The primary network interface

auto eth0 iface eth0 inet dhcp

auto eth1 iface eth1 inet static address 192.168.56.2 netmask 255.255.255.0

Give sudo with no permission to yorrick user: sudo visudo %sudo ALL=(ALL:ALL) NOPASSWD: ALL

Set up a ssh connection with a key-pair (no password) ssh-keygen -t rsa Copy public key to ~/.ssh/authorized_keys (chmod 700 for .ssh dir, 600 for authorized_keys)

Modify your hosts ~/.ssh/config files for

host ubuntu-server-vm Hostname 192.168.56.2 IdentityFile ~/.ssh/app1_rsa

Ssh connection

Activate virtualenv: source ~/virtualenvs/fabric/bin/activate

Test connection to nodes:

Add those lines in ~/.ssh/config

host ubuntu-server-vm User yorrick Hostname 192.168.56.2 IdentityFile ~/.ssh/app1_rsa

Then do

ssh-add ~/.ssh/app1_rsa ssh ubuntu-server-vm

ansible all -m ping (ssh VM_IP must connect for this to work)

Ansible

Apply playbook for config: ansible-playbook -v -i hosts site.yml --tags config

Build war for an application: cd helloworld && mvn clean && mvn package && mv target/helloworld_toto-1.0-SNAPSHOT.war ../roles/app/files/; cd -

Deploy all applications: ansible-playbook -v -i hosts site.yml --tags deploy,test

TODO

• use add line in file instead of copying everything in ansible
• test thread pool in jetty (with continuations in lift)
• see how to connect a broker (JMS by example) to actors
• see how to implement caching in lift with memcached (and a kind of decorator)
• integrate bootstrap in lift app
• set jetty logs path for each app http://webtide.intalio.com/2011/08/sifting-logs-in-jetty-with-logback/
  • copy jars in /usr/share/jetty8/etc/lib/logging/ /ext/
  • add libs in /usr/share/jetty8/etc/start.config ??
  • add 2 config files in /usr/share/jetty8/etc/
  • add config xml files to /usr/share/jetty8/etc/jetty.conf
  • create /usr/share/jetty8/resources/logback.xml with configuration we want
• create a webapp user and put war in it, use this location in jetty and nginx
