If your Kubernetes cluster is not connected to the Internet, you can install SwaggerHub On-Premise in airgapped (offline) mode.
This guide assumes a Kubernetes cluster has been prepared as specified in the Minimum Requirements.
This guide also assumes a private Docker container registry in the network as specified in the Airgapped Installation Requirements.
All commands assume a jumpbox with connectivity to the cluster, and
Download installation files
Before you proceed with the airgapped installation, contact Sales or your account manager and ask for a link to download the installation files. You will receive a link and password to access the download portal. The link is customer-specific and looks like this:
On a computer with Internet access:
Log in to the download portal using the provided link and password.
Select Bring my own cluster on the left.
Download the following files:
- Your license (.yaml)
Latest Kots CLI (kots_linux_amd64.tar.gz) - if not already installed
This version of KOTS CLI is for Linux and WSL. If you are running
kubectlon macOS, you can download the macOS version of KOTS CLI from GitHub:
- Latest Kots Admin Console Airgap bundle (kotsadm.tar.gz)
- Latest SwaggerHub Airgap bundle (SwaggerHub-<version>.airgap)
The total size of the files is about 3 GB.
Copy these files to a temporary directory on your jumpbox.
Install KOTS to kubectl
Here and in the rest of this guide, the commands are to be run on the jumpbox.
SwaggerHub 2.x uses KOTS to manage the installation, licensing, and updates. KOTS is a plugin for
kubectl. SwaggerHub requires KOTS 1.76.1 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, install KOTS:
Unpack the kots_<platform>.tar.gz file. In this example, we unpack it to the kots-cli directory:
mkdir kots-cli tar -zxvf kots_linux_amd64.tar.gz -C kots-cli
cd kots-cli mv kots kubectl-kots
Copy the renamed
kubectl-kotsto anywhere on the
PATH, for example, to
sudo mv kubectl-kots /usr/local/bin/
Verify successful installation:
kubectl kots version
Extract KOTS Admin Console container images and push them into your private Docker container registry:
kubectl kots admin-console push-images ./kotsadm.tar.gz private.registry.host/swaggerhub \ --registry-username rw-username \ --registry-password rw-password
private.registry.host with your registry host and port (if used). Examples: myregistry.example.com, 10.100.20.24:5000.
Registry credentials (
rw-password in the command above) must have push access. These credentials will not be stored anywhere or reused later.
Install Admin Console
The next step is to install the Admin Console using images pushed in the previous step.
Registry credentials provided in this step (
ro-password in the command below) only need to have read access. They will be stored in a Secret in the same namespace where Admin Console will be installed. These credentials will be used to pull the images and will be automatically created as an
imagePullSecret on all of the Admin Console pods.
kubectl kots install swaggerhub \ --kotsadm-namespace swaggerhub \ --kotsadm-registry private.registry.host \ --registry-username ro-username \ --registry-password ro-password
Once this has completed, the KOTS will create a port forward to the Admin Console on port 8800. The Admin Console is exposed internally in the cluster and can only be accessed using a port forward. The port forward will be active as long as the CLI is running. Pressing Ctrl + C will end the port forward.
• Press Ctrl+C to exit • Go to http://localhost:8800 to access the Admin Console
Once this message is displayed, visit
http://localhost:8800 to set up SwaggerHub On-Premise using the Admin Console.
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):
Upload airgap bundle
On the Install in airgapped environment screen, you will be prompted for your Docker container registry details:
Hostname - The registry host in the format
host[:port]. Examples: myregistry.example.com, 10.100.20.24:5000.
Username and Password - Registry credentials with push access.
Registry Namespace - The namespace within the registry where SwaggerHub container images will be pushed. For example, swaggerhub.
At the bottom of the screen, upload the SwaggerHub-n.n.n.airgap file to the indicated drop zone and click Upload airgap bundle.
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:
