Prerequisites
Always review Items' documentation to learn about their specific prerequisites and dependencies.
For hands-on users wishing to deploy, make sure you have covered the basics:
- Access Credentials: Ensure that you have any of the keys, secrets or tokens required by the Item
- Local Prerequisites: Install any tooling needed for deployment, which for instance depending in the item can be:
- Ansible via pypi.org
- Terraform from hashicorp.com
- Helm from helm.sh
ewcclifrom github.com
Item Deployment Best-Practices
There are many good practices you can follow to save yourself or your team the effort of dealing with avoidable security risks or downtime (see Best practices for tenancy management). When it comes to Item deployment specifically, we recommend to at least ensure the following:
- Versioning: Always pin Item versions, for stability, to reduce the blast radius of bugs mistakenly introduce as part of new Item releases and facilitate rollbacks.
- Secret management: Use environment variables or secret managers to temporarily make credentials available for deployment tools.
Deployment Guides
Depending on the item, a first deployment could include the steps to gain access to commonly needed credentials: SSH keys, OpenStack application credentials, Kubeconfig files, etc. You will find instructions as part of each Item's usage documentation.
Beyond the point of authorization, deployment steps are mainly dependent on the Item Technology. For detailed guidance per specific technology, you can get started with these examples:
Deploying By Technology
Ansible Playbook
Run Ansible Playbooks from your local or remote working environment, and configure existing compute instances (read more).
Terraform Module
Learn how to initialize, plan, and apply Terraform modules for provisioning and managing the state of EWC infrastructure (read more).
Deploying via ewccli

The ewccli is a Python package which allows you to deploy them directly into your EWC tenancy, with minimal setup required on your working environment. As simple as `pip install ewccli`, `ewc login`, `ewc hub deploy pytroll` (read more)
