This is a UDS Software Factory bundle intended to be deployed on an RKE2 K8s cluster running in Nutanix. It has been tested using RKE2 clusters deployed with the Nutanix RKE2 module.
A list of included applications can be found here.
Bundle developers see development.md.
For further insight into the underlying infrastructure including the RKE2 cluster, see the Nutanix IAC repo. In particular the UDS SWF pre-requisites documentation. Note that as this bundle continues to be improved the above document may not perfectly capture the required buckets and databases. Also, buckets cannot be created in Nutanix Objects via Terraform/Tofu. Those must be created via click-ops.
To Deploy (required):
- UDS CLI. This links to version 0.16.0 which is what the bundle is tested with but it should work with most nearby versions. The binary is here: https://github.com/defenseunicorns/uds-cli/releases/download/v0.16.0/uds-cli_v0.16.0_Linux_amd64
To Interact with Cluster/Debug (optional). These tools are also baked into the UDS CLI via Zarf (uds zarf tools) but are easier to use if installed directly:
Get the bundle you would like to install:
- You can download the latest in your browser from Defense Unicorn's published packages
- You can pull it via the same protocol used to push/pull container images:
```bash
uds pull oci://ghcr.io/defenseunicorns/uds-bundle/software-factory-nutanix-rke2:0.5.4 --architecture amd64`
```
- You can also reference it by it's "docker name" (OCI image URL) at deploy time with the a similar command to the one above.
```bash
uds deploy oci://ghcr.io/defenseunicorns/uds-bundle/software-factory-nutanix-rke2:0.5.4 --architecture amd64`
```
Create your own uds-config.yaml file. You can start from the reference file in the config/ directory. Note it the default yaml file includes comments to point you at particular docs (such as docs/nexus.md) to guide you in understanding and configuring some of the more challenging values.
Don't worry about the domain, database, TLS, and object store related values at this time. They will be addressed in the following sections.
This bundle requires pre-existing s3 buckets and external postgres databases. The addresses and credentials are passed in via the uds-config.yaml file at deploy time.
Goes without saying, but the k8s cluster must already exist in Nutanix, and you must have admin access to it. We create ours with Terraform/Tofu here. See especially the RKE2 module and module documentation.
During bundle development and testing, we use the *.bigbang.dev domain (which is owned by a Unicorn who used to work for Platform One). You will need to setup routing to *.your-domain.com.
You also need TLS certs signed by a locally trusted CA for the applications. A wildcard cert is convenient, but many security teams prefer a cert per valid sub-domain. Here is a list of all required sub-domains:
-
confluence.your.domain -
gitlab.your.domain -
*.pages.your.domainNote: strongly recommend a wildcard here as it'd be toilsome to keep up with user behavior here. -
registry.your.domain -
gitlab.your.domain -
jira.your.domain -
keycloak.your.domain -
kiali.your.domain -
chat.your.domain -
grafana.your.domain -
neuvector.your.domain -
nexus.your.domain -
*.nexus.your.domainNote: if you create your cert with a SAN per nexus subdomain instead of a wildcard SAN (need one subdomain per image registry) see docs/nexus.md to make sure you update the tenant gateway and other relevant uds-config variables correctly. It was tested with a wildcard SAN on the tenant cert which allowed us to create 1-n registries without performing a bundle deploy to reconfigure networking.
-
sonarqube.your.domain -
tracing.your.domain
Update the domain and TLS cert values in your uds-config.yaml file.
There are the default bucket names in the default uds-config.yaml file. If you choose to deviate from these names know:
- Gitlab only allows you to add a suffix.
- Loki, Velero and Mattermost buckets can be named anything
Reference the uds-config.yaml file you created as you go to be sure you're creating/have created buckets by the intended names. For a list of UDS config variables to be sure you update, see docs/object-store-creation-and-configuration.md.
The following applications require an external database:
- Keycloak
- Gitlab
- Sonarqube
- Jira
- Confluence
- Mattermost
- Nexus
Update your uds-config.yaml file with the correct credentials and connection URLs. For a list of UDS config variables to be sure you update, see docs/database-creation-and-configuration.md.
You can review the Terraform module we use for provisioning postgres databases with Nutanix Database Service in our delivery-nutanix-iac repo.
This bundle utilizes the Nutanix CSI Helm chart for persistent storage. It needs Nutanix resources set up ahead of time.
- Prism Element user and password for the CSI provider to connect to Prism Element. Update your
uds-config.yamlfile with the user credentials and the Prism Element IP/Hostname. - Prism Central user and password for the CSI provider to connect to Prism Central. Update your
uds-config.yamlfile with the user credentials and the Prism Central IP/Hostname. - Nutanix Storage Container for RWO persistent volumes. Add the storage container name to the
uds-config.yaml. - Nutanix File Server for RWX persistent volumes. Be sure to configure the DNS records that it asks for. Put the File Server name as it appears in Prism Element into your
uds-config.yaml.
NOTE: User/password and Nutanix File server must be configured in Prism Element not Prism Central.
This is the easy step.
- Set
KUBECONFIGto point to the kubernetes kubeconfig file. - Set
UDS_CONFIGto point at youruds-config.yamlfile. - Run
uds deploy <package file name or OCI url> --architecure amd64.
If you got the config right the first time, then congratulations! The whole thing is now running. If murphy struck, see the developer docs for guidance on efficiently testing configuration changes, setting up multiple clusters in a way that fits with the uds tasks, and other notes.
