CHAPTER 1

Guides

1.1 Developer Guide

The document walks you through installing the necessary packages and environment preparations in order to build thecloud installer.

1.1.1 Base system

Development and testing is done on Ubuntu and using a release of Trusty or later.

1.1.2 Building cloud installer

Note: Although not required, Sbuild is the preferred way for building the package set. Please refer to this wiki pageon setting up sbuild.

Just like the base system the sbuild chroots need to be Trusty or later, but the architecture of the chroots does notmatter.

Once sbuild is configured, checkout the source code of the installer:

$ git clone https://github.com/Ubuntu-Solutions-Engineering/cloud-installer.git ~/cloud-installer$ cd cloud-installer

Use the target ‘install-dependencies’ to install a custom binary package for the build dependencies:

$ make install-dependencies

From here you can build the entire package set by running:

$ make sbuild# or, if you prefer not to use sbuild:$ make deb

Once finished your packages will be stored in the top level directory where your cloud-installer project is kept.

$ ls ../*.deb

3

https://wiki.ubuntu.com/SimpleSbuild


1.1.3 Running the cloud installer

Running the installer for test currently requires installing the packages. After building the packages using either ‘makedeb’ or ‘make sbuild’, you can install and run with the ‘run’ target:

$ sudo make run type=single# or$ sudo make run type=multi

You can also set the MAAS_HTTP_PROXY env var for the cloud-install command like this:

$ sudo make run type=single proxy=http://myproxy/

If you are running the landscape installer, you will want to use the ‘landscape’ target:

$ sudo make landscape proxy=http://myproxy/

1.1.4 Running the Pegasus status screen

If you have run the installer and are working on changes to the status screen (in cloudinstall/), you can re-run the statusscreen with the correct python path using this target:

$ make status

If you are testing the status screen’s code for deploying charms, you may need to first start your juju environment overfrom scratch:

$ juju destroy-environment local$ juju bootstrap$ make status

1.1.5 Changing the log level

The cloud-status program logs to ~/.cloud-install/commands.log. The default log level for that log is “DEBUG”. Mostof the program logs at the DEBUG level, which is the most verbose that is currently defined. If you want a different loglevel, you can set the UCI_LOGLEVEL environment variable. Your choices are “DEBUG”, “INFO”, “WARNING”,“ERROR”, and “CRITICAL”.

$ UCI_LOGLEVEL=ERROR cloud-status

1.1.6 Building documentation

Documentation will be built in docs/_build/html, and requires Sphinx to build.

$ cd docs && make html

1.1.7 Running Tests

Tests can be ran against a set of exported data(default) or a live machine. In order to test against live data the followingenvironment variable is used.

$ JUJU_LIVE=1 nosetests3 test

4 Chapter 1. Guides


For the python code, using pep8 and pyflakes is encouraged:

$ make pyflakes$ make pep8

1.2 Single Installer Guide

1.2.1 Pre-requisites

Add the cloud-installer ppa to your system.

$ sudo apt-add-repository ppa:juju/stable$ sudo apt-add-repository ppa:cloud-installer/experimental$ sudo apt-get update

Note: Adding the ppa is only necessary until an official release to the archives has been announced.

1.2.2 Recommended Hardware

The installer would work best with at least:

• 12G RAM

• 100G HDD (SSD for optimal performance)

• 8 CPUS

1.2.3 Installation

Install the cloud-installer via apt-get

$ sudo apt-get install cloud-installer

1.2.4 Start the installation

To start the installation run the following command

$ sudo cloud-install

Note: The installer should be run as a non-root user.

Optional Flags

Options:-c <file> POSIX shell script to be sourced by installer

automating install by pre-setting menu responses.-s enable swift-storage-i install only (don’t invoke cloud-status)-u uninstall the cloud-h print this message

1.2. Single Installer Guide 5


Note: Enabling swift storage requires at least 3 instances and another additional instance for swift-proxy.

Note: If you wish to deploy services to this openstack using juju you will need to enable swift storage.

An initial dialog box will appear asking you to select which type of install, choose Single system.

1.2.5 Setting a password

When asked to set the openstack password it should be noted that this password is used throughout all openstackrelated services (ie Horizon login password).

1.2.6 Installing of Services

The installer will run through a series of steps starting with making sure the necessary bits are available for a singlesystem installation and ending with a juju bootstrapped system.

When the bootstrapping has finished it will immediately load the status screen. From there you can see the nodes listedalong with the deployed charms necessary to start your private openstack cloud.

Adding additional compute nodes, block storage, object storage, and controllers can be done by pressing A and makingthe selection on the dialog box.

Finally, once those nodes are displayed and the charms deployed the horizon dashboard will be available to you formanaging your openstack cloud.

1.2.7 Logging into Horizon (Openstack Dashboard)

The login credentials for the dashboard are:

• username: ubuntu

• password: “password that was set during installation”

1.2.8 Troubleshooting

The installer keeps its own logs in $HOME/.cloud-install/commands.log.

1.2.9 Uninstalling

To uninstall and cleanup your system run the following

$ sudo cloud-install -u

1.3 Multi Installer Guide

1.3.1 Pre-requisites

Multi-Installer has been tested on Ubuntu Server, which is the recommended OS for the cloud installer.

6 Chapter 1. Guides


Add the cloud-installer ppa to your system.

$ sudo apt-add-repository ppa:juju/stable$ sudo apt-add-repository ppa:maas-maintainers/stable$ sudo apt-add-repository ppa:cloud-installer/ppa$ sudo apt-get update

Note: Adding the ppa is only necessary until an official release to the archives has been announced.

1.3.2 Installation

Install the cloud-installer via apt-get

$ sudo apt-get install cloud-installer

1.3.3 Start the installation

To start the installation run the following command

$ sudo cloud-install

Note: The installer should be run as a non-root user.

An initial dialog box will appear asking you to select which type of install, choose Multi-system.

1.3.4 Setting a password

When asked to set the openstack password it should be noted that this password is used throughout all openstackrelated services (ie Horizon login password). The only service that does not use this password is juju-gui.

1.3.5 Next Steps

The installer will run through a series of steps starting with making sure the necessary bits are available for a multisystem installation and ending with a juju bootstrapped system.

1.3.6 Troubleshooting

The installer keeps its own logs in $HOME/.cloud-install/commands.log.

1.3.7 Uninstalling

To uninstall and cleanup your system run the following

$ sudo cloud-install -u

1.3. Multi Installer Guide 7


1.4 Using Juju in Openstack

Once the Openstack cloud has been deployed there are only a couple of steps to enable juju to deploy charms into theprivate cloud.

Note: Juju requires swift storage so this needs to have been enabled during the install.

1.4.1 Update ~/.juju/environments.yaml

In the users ~/.juju/environments.yaml file there is a a openstack stanza.

openstack:type: openstackuse-floating-ip: trueuse-default-secgroup: truenetwork: ubuntu-netauth-url: http://keystoneurl:5000/v2.0/tenant-name: ubunturegion: RegionOneauth-mode: userpassusername: ubuntupassword: pass

The credentials are already filled out for you, however, you’ll need to set the auth-url to your Keystone public address.

1.4.2 Bootstrap Juju

Once the environments are updated run:

$ juju switch openstack$ juju metadata generate-image -i <image_id> -s trusty$ juju sync-tools$ juju bootstrap --metadata-source /home/ubuntu

Now you can deploy charms within your Openstack cloud.

Note: <image_id> is found in the horizon dashboard http://<public-ip>/horizon/project/images/
