This guide contains the steps to install SwaggerHub On-Premise to an existing Kubernetes cluster. When complete, the SwaggerHub application will be deployed in the chosen namespace in the cluster.
This guide assumes a Kubernetes cluster has been prepared as specified in the Minimum Requirements.
All commands assume a jumpbox with connectivity to the cluster, and
Prepare the jumpbox
Connect to the jumpbox using SSH as an administrative user.
kubectlis set up to contact the cluster. A quick test would list the nodes, expecting to see several listed like this:
$ kubectl get node NAME STATUS ROLES AGE VERSION ip-10-100-1-2.ec2.internal Ready <none> 33d v1.21.2-13+d2965f0db10712 ip-10-100-1-3.ec2.internal Ready <none> 33d v1.21.2-13+d2965f0db10712 ip-10-100-1-4.ec2.internal Ready <none> 33d v1.21.2-13+d2965f0db10712
kubectlhas permissions to perform the installation. Run the following command - the answer should be yes:
$ kubectl auth can-i create clusterrole -A yes
Install KOTS to kubectl
SwaggerHub 2.x uses KOTS to manage the installation, licensing, and updates. KOTS is a plugin for
kubectl. SwaggerHub requires KOTS 1.68.0 or later.
First, check if KOTS is already installed:
$ kubectl kots version
If you see
Replicated KOTS 1.x.x and the version is:
If you see the “unknown command” error, proceed to install KOTS.
The easiest way to install KOTS is to run this one-liner command:
$ curl https://kots.io/install | bash
If you do not have root access or cannot write to the
/usr/local/bin directory, you can download and install KOTS manually:
Download the latest release for your operating system from:
Linux and macOS are supported.
Unpack the release.
Copy the renamed
kubectl-kotsto anywhere on the
Launch the installation
Choose a new namespace for SwaggerHub On-Premise that does not conflict with any existing in your cluster. In this guide, we will use swaggerhub.
The following will begin the installation process. It will:
Deploy an administration server to the cluster.
Ask for a new password for the administration service. Provide a new password, record it, and keep it safe.
When the server is ready, it will create a port forward to be accessible from the install VM.
To install, run this command:
$ kubectl kots install swaggerhub --namespace swaggerhub
You will then be prompted to enter a password for the administration console:
* Deploying Admin Console * Creating namespace [x] * Waiting for datastore to be ready [x] Enter a new password to be used for the Admin Console: ******** * Waiting for Admin Console to be ready [x] * Press Ctrl+C to exit * Go to http://localhost:8800 to access the Admin Console
At this point, the base installation is finished. You can press Ctrl + C anytime to end the port forwarding session to the Admin Console.
At any time in the future, you can resume port forwarding to the Admin Console with this command and finish the session with Ctrl + C.
$ kubectl kots admin-console --namespace swaggerhub • Press Ctrl+C to exit • Go to http://localhost:8800 to access the Admin Console
If SSH is routing to this console, for example a jumpbox situation, port forwarding will be needed to access the admin console from a local desktop. The example below will show how to tunnel from the administrator’s desktop to the jumpbox VM using SSH, which will then open port 8800 to reach the administrator console.
General example to tunnel from the administrator’s desktop:
Upload the license
http://localhost:8800 and log in to the Admin Console using the administrator password that you set during deployment.
On the next screen, you will be asked to upload your SwaggerHub license file (.yaml):
If your SwaggerHub license supports airgapped (offline) installations, you will see an option to proceed with the airgapped setup. Since you are installing SwaggerHub in online mode, click Download SwaggerHub from the Internet.
On the next page, you can specify the configuration settings for SwaggerHub. The required settings are:
DNS name for SwaggerHub - Specify a public or internal domain name that will be used to access SwaggerHub on your network. For example, swaggerhub.mycompany.com.
This domain name must already be registered in your DNS service. You will need to point it to the ingress controller.
Database settings - Choose between internal or external databases. If using external databases, you need to specify the database connection strings.
It will not possible to switch from internal to external databases or vice versa after the initial configuration.
SMTP settings - Specify an SMTP server for outgoing email.
Other settings are optional and depend on your environment and the desired integrations. Most settings can also be changed later. See SwaggerHub Configuration for a description of the available settings.
The next step checks your Kubernetes cluster to ensure it meets the minimum requirements.
If all preflight checks are green, click Continue.
If one or more checks fail, do not proceed with the installation and contact Support.
While the installer allocates resources and deploys workloads, the application status on the dashboard will be Unavailable. If it stays in this state for more than 10 minutes, generate a support bundle and send it to the Support team.
Tip: To monitor the deployment progress, you can run
kubectl get pods -n swaggerhub
a few times until all pods are Running or Completed:
NAME READY STATUS RESTARTS AGE kotsadm-85d89dbc7-lwvq2 1/1 Running 0 32m kotsadm-minio-0 1/1 Running 6 13d kotsadm-postgres-0 1/1 Running 5 13d spec-converter-api-584cc46657-hbfmd 1/1 Running 0 9m55s swagger-generator-v3-6fc55cb57d-brwg6 1/1 Running 0 9m55s swaggerhub-accounts-api-8bb87565b-xthkv 1/1 Running 0 9m55s swaggerhub-api-service-546b56b94b-6jxch 1/1 Running 0 9m55s swaggerhub-configs-api-794847bd79-jnlhl 1/1 Running 0 9m55s swaggerhub-custom-rules-5ccfd45599-d5bxc 1/1 Running 0 9m55s swaggerhub-frontend-69b7c55595-n7vsj 1/1 Running 0 9m55s swaggerhub-notifications-bbd5f8794-ggz99 1/1 Running 0 9m55s swaggerhub-operator-758c997747-hnjt7 1/1 Running 0 9m55s swaggerhub-pre-install-r9c2f 0/1 Completed 0 13d swaggerhub-pre-upgrade-cg664 0/1 Completed 0 10m swaggerhub-products-api-6dd446b654-7w7wn 1/1 Running 0 9m55s swaggerhub-registry-api-886997fd7-8q8c7 1/1 Running 0 9m54s swaggerhub-virtserver-79fdf54f98-wpmt8 1/1 Running 0 9m54s
Once the application has become ready, the status indicators on the Dashboard become green.
Create admin user and default organization
Run the following command to create an admin user and a default organization in SwaggerHub. Note the space in
kubectl exec -it deploy/swaggerhub-operator -n swaggerhub -- cmd create-admin-user admin -p p@55w0rd firstname.lastname@example.org myorg
The admin username must be between 3 to 20 characters and can only contain characters
A..Z a..z 0..9 - _ .
The admin password must be at least 7 characters long with at least 1 lowercase letter and 1 number. If the password contains characters that have a special meaning in Bash (such as
! $ &and others), enclose the password in single quotes (like
-p '$passw0rd') or escape the special characters.
Once done, open the SwaggerHub web application at
http://DNS_NAME and log in using the admin username and password. You should see the created organization in the sidebar:
