Configure Simplestreams for a private cloud

When Juju bootstraps a cloud, it needs two critical pieces of information:

The uuid of the image to use when starting new compute instances.

The URL from which to download the correct version of a tools tarball.

The essential information above is actually stored in two json files in simplestreams.

To learn more details ,you can refer here.

Before configuring the simplestreams, we need to do some preparations:

Upload Ubuntu 14.04LTS(Trusty) and Ubuntu 16.04LTS(Xenial) image to Openstack

Trusty image

Xenial image

Choose xxxxx-server-cloudimg-amd64-disk1.img to download.

Upload the images to openstack:

upload_image1

upload_image2

Install Apache server

sudo apt-get install apache2

Generate image json file for simplestreams:

sudo mkdir /var/www/html/stack
sudo juju metadata generate-image -a amd64 -i 843bef24-8c70-40e1-a380-972717c9e4b3 -r RegionOne -s xenial -d /var/www/html/stack -u http://172.16.1.3:5000/v2.0 -e openstack

Regarding the command-line flags used:

  • -i 843bef24-8c70-40e1-a380-972717c9e4b3: specifies the ID of the Glance image that we just created before.
  • -u http://172.16.1.3:5000/v2.0: specifies the Keystone URL, and should match the value from the auth-url field of our environment as specified in $HOME/.juju/environments.yaml.
  • -e openstack: identifies the Juju environment described in $HOME/.juju/environments.yaml file.
  • -s xenial: specifies the image series (the Ubuntu release name).
  • -a amd64: specifies the CPU architecture.
  • -d /var/www/html/stack: specifies the base directory where the metadata will be written to. For images, the path will be /opt/stack/images/streams/v1..

Generate tools json file for simplestreams:

juju metadata generate-tools -d /var/www/html/stack/ --stream released

Tips:

/var/www/html is the default directory of Apache server

Download tool files:

Download link

Download and put it in the directory /var/www/html/stack/tools/released

Tips:

Download the files that match Juju and operating system version

Change the files permission

cd /var/www/html
sudo chmod -R 777 stack

Use the validation commands to ensure image and tools are available for juju to use:

juju metadata validate-images
juju metadata validate-tools

Bootstrap Juju

juju switch openstack
juju bootstrap

And then you can try to deploy services by using juju deploy, for example:

juju deploy juju-gui
