Note: This provider is in "beta" and makes use of manual provisioning. Manual provisioning allows Juju users to implement any cloud provider's API calls and acts similar to a standard provider implemented via the Juju project. You can access the provider source code on github
This package provides a CLI plugin for Juju that allows automated provisioning of C1 BareMetal SSD servers on Scaleway.
Scaleway is the first IaaS provider worldwide to offer an ARM based cloud. It’s the ideal platform for horizontal scaling. The solution provides on-demand resources: SSD storage, movable IPs, images, security groups, and object storage.
This plugin is highly inspired from kAPIlt Juju plugins.
Note: This process requires you to have an Scaleway account.
- You have an account and are logged into cloud.scaleway.com
- You have configured your SSH Key
- You have installed libffi-dev and libssl-dev
Plugin installation is done via 'pip', the Python package manager, available by default on Ubuntu.
A virtualenv is also recommended to sandbox this install from your system packages:
pip install -U juju-scaleway
Before you can start using Juju with Scaleway, you will need to get an API token. API tokens are unique identifiers associated with your Scaleway account.
To get one, open the pull-down menu on your account name and click on the "My Credentials" link.
Then, to generate a new token, click the "Create New Token" button on the right corner.
In a terminal, export your credentials required by the plugin using environment variables:
export SCALEWAY_ACCESS_KEY=<organization_key> export SCALEWAY_SECRET_KEY=<secret_token>
Note: As environment variables are not shared between shells, you will
need to repeat this operation for every shell. You can avoid this repetition
by adding this environment variables in your shell's rc files, for instance
append them to your
Next, add an environment for Scaleway in '~/.juju/environments.yaml'. This environment will look like the following:
# https://jujucharms.com/docs/config-scaleway.html scaleway: type: manual bootstrap-host: null bootstrap-user: root
Then, tell Juju which environment to use:
Set Scaleway as your default provider by running:
juju switch scaleway
You can now bootstrap your Scaleway environment. You need to route the command through the scaleway plugin that we installed via pip:
juju scaleway bootstrap
All machines created by this plugin will have the Juju environment name as a
prefix for their servers name, for instance
After your environment is bootstrapped you can add additional machines to it
add-machine command, for instance the following will add 2 additional
juju scaleway add-machine -n 2 juju status
You can now use standard Juju commands to deploy services via charms:
juju deploy wordpress
If you don't specify a machine to place the workload on, the machine will automatically go to an unused machine within the environment.
You can use manual placement to deploy target particular machines:
juju deploy mysql --to=2
This command deploys a mysql unit to the server number #2
Assemble these workloads together via relations like Lego blocks:
juju add-relation wordpress mysql
You can list all machines in Scaleway that are part of the Juju environment with the list-machines command. This directly queries the Scaleway API and does not interact with the Juju API:
juju scaleway list-machines Id Name Status Created Address 6222349 scaleway-0 active 2014-11-25 126.96.36.199 6342360 scaleway-ef19ad5cc... active 2014-11-25 188.8.131.52 2224321 scaleway-145bf7a80... active 2014-11-25 184.108.40.206
You can terminate allocated machines via their machine id. By default, the Scaleway plugin forces the termination of machines, which also terminates any service unit running on on those machines:
juju scaleway terminate-machine 1 2
And you can destroy the entire environment via:
juju scaleway destroy-environment
destroy-environment command also takes a --force option which only uses
the Scaleway API. It's helpful if the state server or other machines are
killed independently of Juju.
