Installing LAMP with puppet on Docker
bogotobogo.com site search:
Note
In this article, we'll install LAMP on Ubuntu 14.04 within Docker container. This is not much different from a simple install of LAMP via puppet (puppet install on ubuntu 14.04) except our work is done within Docker. Only difference is just one command at the beginning:
$ docker run -it ubuntu:14.04 ... root@374a0b304efe:/#
Puppet with Amazon EC2 : Install LAMP with a Single Manifest
We'll develop a manifest on a Puppet agent node, and execute it via puppet apply.
In the process, we learn how to write a manifest using the following types of resource declarations:
- exec: to execute commands, such as apt-get
- package: to install packages via apt
- service: to ensure that a service is running
- file: to ensure that certain files exist
Installing puppet agent
Install puppet agent:
root@374a0b304efe:/# apt-get update root@374a0b304efe:/# apt-get install puppet
Creating a Manifest
Puppet has been installed. Now, let's create a new manifest:
$ sudo vi /etc/puppet/manifests/lamp.pp
Add the following lines to declare the resources that we just determined we wanted. The inline comments detail each resource declaration:
# execute 'apt-get update'
exec { 'apt-update': # exec resource named 'apt-update'
command => '/usr/bin/apt-get update' # command this resource will run
}
# install apache2 package
package { 'apache2':
require => Exec['apt-update'], # require 'apt-update' before installing
ensure => installed,
}
# ensure apache2 service is running
service { 'apache2':
ensure => running,
}
# install mysql-server package
package { 'mysql-server':
require => Exec['apt-update'], # require 'apt-update' before installing
ensure => installed,
}
# ensure mysql service is running
service { 'mysql':
ensure => running,
}
# install php5 package
package { 'php5':
require => Exec['apt-update'], # require 'apt-update' before installing
ensure => installed,
}
# ensure info.php file exists
file { '/var/www/html/info.php':
ensure => file,
content => '<?php phpinfo(); ?>', # phpinfo code
require => Package['apache2'], # require 'apache2' package before creating
}
Applying the Manifest - "puppet apply"
Now we will use the puppet apply command to execute the manifest. On ip-172-31-25-70 node, run this:
root@374a0b304efe:/# puppet apply /etc/puppet/manifests/lamp.pp Notice: Compiled catalog for 374a0b304efe.attlocal.net in environment production in 0.78 seconds Notice: /Stage[main]/Main/Exec[apt-update]/returns: executed successfully Notice: /Stage[main]/Main/Service[mysql]/ensure: ensure changed 'stopped' to 'running' Notice: Finished catalog run in 13.69 seconds
The apache2 seems to be running fine:
root@374a0b304efe:/# ps -ef|grep apache2 root 5622 1 0 02:45 ? 00:00:00 /usr/sbin/apache2 -k start www-data 5625 5622 0 02:45 ? 00:00:00 /usr/sbin/apache2 -k start
Creating a LAMP image
We successfully installed the LAMP, however, to use port 80, and see the web page, we need to set port forwarding. Let's close our Docker, and resume it with port option. First, we need to created the image we worked on using the image id, 374a0b304efe.
$ docker commit -m "LAMP added to Ubuntu14" -a "bogo" 374a0b304efe bogo-lamp 14c9538ef4e43f7fe82184e443cec0f4fa8fd528438d9dbc2ac354b95c39e0b4
Here we used the docker commit command. We specified two flags: -m and -a. The -m flag allows us to specify a commit message, much like we would with a commit on a version control system. The -a flag allows us to specify an author for our update.
We also specified the container we want to create this new image from, 374a0b304efe (the ID we recorded earlier) and we specified a target for the image:
bogo-lamp
Let's see what images we have:
$ docker images REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE bogo-lamp latest 14c9538ef4e4 About a minute ago 401 MB ubuntu 14.04 91e54dfb1179 4 weeks ago 188.4 MB
Docker run with port forwarding
Then, resume our container with the image we created in previous section:
$ docker run -it -p 9999:80 bogo-lamp
What we did is forwarding port from host port 9999 to docker's port 80.
On docker, let's run apache2 server:
root@0a873afa3bde:/# service apache2 restart * Restarting web server apache2
