Web server setup

sudo adduser $USER www-data
sudo chgrp www-data /var/www/
sudo chmod g+rwX /var/www/
sudo rm -f /var/www/html/index.html

Setting up the server itself

This assumes all the above was installed and done, that the code is running as an "ubuntu" user in its default home directory, on a server accessible at system-image.test.com with a valid SSL certificate on port 443.

bzr branch lp:~ubuntu-system-image/ubuntu-system-image/server system-image
cd system-image
tools/generate-keys
tox
cp -R tests/keys/*/ secret/gpg/keys/
bin/generate-keyrings

At this stage, you have the branch on your system, have generated some GPG keys (albeit test ones) and generated the matching keyrings. It's now time to configure the system by creating "etc/config" containing:

[global]
base_path = /home/ubuntu/system-image/
channels = test
gpg_key_path = secret/gpg/keys/
gpg_keyring_path = secret/gpg/keyrings/
publish_path = /var/www/
state_path = state/
public_fqdn = system-image.test.com
public_http_port = 80
public_https_port = 443

[channel_test]
type = auto
versionbase = 1
fullcount = 15
files = ubuntu, device, custom-savilerow, keyring, version
file_ubuntu = remote-system-image;https://system-image.ubuntu.com;trusty-proposed;ubuntu
file_device = remote-system-image;https://system-image.ubuntu.com;trusty-proposed;device;keyring=archive-master
file_custom-savilerow = http;https://jenkins.qa.ubuntu.com/job/savilerow-watch/lastSuccessfulBuild/artifact/custom.tar.xz;name=custom-savilerow,monitor=https://jenkins.qa.ubuntu.com/job/savilerow-watch/lastSuccessfulBuild/artifact/build_number
file_keyring = keyring;archive-master
file_version = version

You may want to look at config.example for all possible key values.

The above defines a server accessible at system-image.test.com, which listens for http on port 80 and for https on port 443, has one channel that's managed by the importer, that channel is configured to contain 5 tarballs:

• ubuntu => Ubuntu root filesystem, imported as-is from system-image.ubuntu.com

• device => Device tarball, imported from system-image.ubuntu.com and then repacked to swap the GPG keys

• custom-savilerow => Imported from an http server (customization tarball)

• keyring => Contains the GPG keys that override those from the ubuntu tarball

• version => Contains the channel configuration and current build data

Now that the configuration is done, we need to actually create the channels, add a device and publish the keyrings, for that, run "bin/si-shell" and do:

pub.create_channel("test")
pub.create_device("test", "mako")
for keyring in ("archive-master", "image-master", "image-signing", "blacklist"):
    pub.publish_keyring(keyring)

At this point, your server is ready, all you need to do now is generate images by running: bin/import-images
