Atmosphere

If you have any questions and discussions about Atmosphere, you can join the community:

Quick Start

The quick start intends to provide the most near-production experience possible, as it is architected purely towards production-only environments. In order to get a quick production-ready experience of Atmosphere, you will need access to an OpenStack cloud.

The quick start is powered by Molecule and it is used in continuous integration running against the VEXXHOST public cloud so that would be an easy target to use to try it out.

You will need the following quotas set up in your cloud account:

  • 8 instances
  • 32 cores
  • 128GB RAM
  • 360GB storage

These resources will be used to create a total of 8 instances broken up as follows:

  • 3 Controller nodes
  • 3 Ceph OSD nodes
  • 2 Compute nodes

First of all, you'll have to make sure you clone the repository locally to your system with git by running the following command:

git clone https://github.com/vexxhost/atmosphere

You will need poetry installed on your operating system. You will need to make sure that you have the appropriate OpenStack environment variables set (such as OS_CLOUD or OS_AUTH_URL, etc.). You can also use the following environment variables to tweak the behaviour of the Heat stack that is created:

  • ATMOSPHERE_STACK_NAME: The name of the Heat stack to be created (defaults to atmosphere).

  • ATMOSPHERE_PUBLIC_NETWORK: The name of the public network to attach floating IPs from (defaults to public).

  • ATMOSPHERE_IMAGE: The name or UUID of the image to be used for deploying the instances (defaults to Ubuntu 20.04.3 LTS (x86_64) [2021-10-04]).

  • ATMOSPHERE_INSTANCE_TYPE(Deprecated): The instance type used to deploy all of the different instances.(It doesn't have its own default value.) This has been deprecated from v1.4.0. You can configure the instance type per a machine role using ATMOSPHERE_CONTROLLER_INSTANCE_TYPE, ATMOSPHERE_COMPUTE_INSTANCE_TYPE, and ATMOSPHERE_STORAGE_INSTANCE_TYPE variables. For backwards compatibility, if variables specific to the machine roles are not set and ATMOSPHERE_INSTANCE_TYPE is set, ATMOSPHERE_INSTANCE_TYPE value is used.

  • ATMOSPHERE_CONTROLLER_INSTANCE_TYPE: The instance type used to deploy controller instances (defaults to v3-standard-16).

  • ATMOSPHERE_COMPUTE_INSTANCE_TYPE: The instance type used to deploy compute instances (defaults to v3-standard-4).

  • ATMOSPHERE_STORAGE_INSTANCE_TYPE: The instance type used to deploy storage instances (defaults to v3-standard-4).

  • ATMOSPHERE_NAMESERVERS: A comma-separated list of nameservers to be used for the instances (defaults to 1.1.1.1).

  • ATMOSPHERE_USERNAME: The username what is used to login into the instances ( defaults to ubuntu).

  • ATMOSPHERE_DNS_SUFFIX_NAME: The DNS domainname that is used for the API and Horizon. (defaults to nip.io).

  • ATMOSPHERE_ACME_SERVER: The ACME server, currenly this is from LetsEncrypt, with StepCA from SmallStep it is possible to run a internal ACME server. The CA of that ACME server should be present in the instance image.

  • ATMOSPHERE_ANSIBLE_VARS_PATH: The path for ansible group_vars and host_vars. This to build a multinode development cluster with own configs, that are not generated by molecule. This way you can test your configs before you bring them to production.

Once you're ready to get started, you can run the following command to install poetry dependencies:

poetry install

Then you can run the following command to build the Heat stack :

poetry run molecule converge

This will create a Heat stack with the name atmosphere and start deploying the cloud. Once it's complete, you can login to any of the systems by using the login sub-command. For exampel, to login to the first controller node, you can run the following:

poetry run molecule login -h ctl1

In all the controllers, you will find an openrc file location inside the root account home directory, as well as the OpenStack client installed there as well. You can use it by running the following after logging in:

source /root/openrc
openstack server list

The Kubernetes administrator configuration will also be available on all of the control plane nodes, you can simply use it by running kubectl commands on any of the controllers as root:

kubectl get nodes -owide

Once you're done with your environment and you need to tear it down, you can use the destroy sub-command:

poetry run molecule destroy

For more information about the different commands used by Molecule, you can refer to the Molecule documentation.

Contributing

You'll need to make sure that you have pre-commit setup and installed in your environment by running these commands:

pre-commit install --hook-type commit-msg
