Please consider the following prerequisites regarding Scheer PAS API Management.
API Management uses Docker to provide a simple setup which is easy to update and scalable if necessary. |
Make sure you have network access during the installation, because you have to download images from Docker hub. |
Download the following files provided by Scheer to the folder you want to install API Management to:
api-mgmt-gateway-<VERSION>.tar
api-mgmt-ui-<VERSION>.tar
api-mgmt-keycloak-<VERSION>.tar
api-mgmt-<VERSION>.zip
Later on, in step 6, you will need file apiman-default-config.json from the api-mgmt-<VERSION>.zip on an API Management client. You can copy the ZIP file to your client now (or later), or download the needed file from this page in step 6. |
Extract api-mgmt-<VERSION>.zip.
Extracting this file will create a folder api-mgmt which is required permanently. It contains configuration files with sensitive data such as passwords, so access to this folder should be restricted. The Docker container however must be able to read the data.
Load the Docker images:
Configure the installation settings in the Docker .env file as described below. This file resides in folder api-mgmt\single-host-setup\.
.env is a hidden file. |
Setting | Description | Default Value | ||
---|---|---|---|---|
BRIDGE_URL | Provide your BRIDGE hostname(s). You may specify more than one URL as a comma-separated list.
| bridge.acme-corp.com | ||

| true | ||
TRUSTSTORE_KEYSTORE_PASSWORD | Provide the password of the Java truststore file that contains the certificates. This password will also be used if you create a keystore with our script to generate self-signed certificates (see section Installing API Management#Use Self-Signed Certificate below).
| secret | ||
UI_PORT | Provide the port to access the API Management user interface. | 8443 |
You need a certificate to establish secure connections between clients and API Management, as well as between the different components of API Management itself. You can use an official certificate, or you can create a self-signed one. |
We recommend using an official and valid certificate. |
Folder api-mgmt\configs already contains an example structure of the needed files. |
This setup is designed to run on one host only. The SSL KeyStore is shared between all services. |
To use your official certificate, proceed as follows:
Create a Java keystore which includes the certificate. The keystore must be secured by a store password. Assign the name apiman.jks to the keystore file.
Refer to Certificates and Keystores for some hints on certificate handling.
Update the following entries in the Docker .env file (see table above for details):
Update entry TRUSTSTORE_KEYSTORE_PASSWORD
with the store password.
Set entry SELF_SIGNED
to false.
If you have certificates and intermediate certificates, please consult the keycloak documentation Keycloak Docker image > Setting up TLS(SSL).
If you do not possess a valid certificate, you can create a self-signed one. You can use Java Keytool to do this.
Generate a keystore. To do this, run the following command from folder api-mgmt/single-host-setup (folder containing the file docker-compose.yml):
docker-compose run --no-deps --rm --entrypoint '/opt/api-mgmt/create-self-signed-certificates.sh' keycloak |
Some shells (e.g. git bash) have problems with the path so you may have to escape the slashes with backslash like |
On Linux make sure that docker is able to write to the configs folder:
|
Copy the following generated files from folder api-mgmt/configs/ self-signed-certificates to folder api-mgmt/configs/:
apiman.jks
Keycloak is an open source identity and access management solution and is used to create and manage the users of API Management and OAuth2 secured APIs. |
Before you can start the Docker containers, you need to change some of the Keycloak settings in the Docker configuration file .env. The values you need to replace the default values with, are to be obtained from your Keycloak instance.
Start Keycloak. To do this, run the following command from folder api-mgmt/single-host-setup (folder containing the file docker-compose.yml):
docker-compose up keycloak |
Keycloak has been started when the log reads something like
[...] Keycloak 7.3.0 (WildFly Core 6.0.2.Final) started in 50476ms - Started 673 of 933 services [...] |
Open your Keycloak URL, e.g. https://api.acme-corp.com:8445/auth/admin, and login to the administration console. To login, use username and password as configured in the .env file.
Change the Valid Redirect URIs of the below listed clients.
Navigate to Clients. You will have to change the settings for the following clients:
| |
Open tab Settings for each of the two clients by clicking on the client ID in the list, and change the entry in field Valid Redirect URIs to match your setup:
|
Now, change all default credentials for clients apiman , apimanui , apiman-gateway-api and kibana and copy the new passwords to the Docker configuration file.
Setting | Description | Default Value |
---|---|---|
KEYCLOAK_APIMAN_SECRET | Provide the secret for client apiman generated in Keycloak. | password |
KEYCLOAK_GATEWAY_SECRET | Provide the secret for client apiman-gateway-api generated in Keycloak. | password |
KEYCLOAK_APIMANUI_SECRET | Provide the secret for client apimanui generated in Keycloak. | password |
KEYCLOAK_REALM_PUBLIC_KEY | Provide the realm public key generated in Keycloak. | MIGfMA0GCSqGSIb3DQEBAQU[...] |
API Mgmt 7.4.0 KEYCLOAK_KIBANA_SECRET
| Provide the secret for client kibana generated in Keycloak. |
password
|
Do this as follows:
Navigate to Clients. You will have to change the settings for the following clients:
| |
For each client, go to tab Credentials and click Regenerate Secret. In the Docker .env file,
| |
In Realm Settings go to tab Keys. Navigate to tab Providers and delete provider rsa. | |
Next, choose rsa-generated from select box Add keystore. | |
In the upcoming dialog, set Key size to the maximum available value and save your changes. | |
Go back to tab Active and click Public key. | |
The key will be displayed in a separate pop-up window. Copy the key and paste it to variable |
All Keycloak-related settings have been configured now, and you need to stop docker-compose and restart all containers.
Stop the Keycloak container by pressing Ctrl-C.
Check the configuration, if necessary.
You can check, if everything has been configured, with
This command will list the Docker configuration and will throw warnings, if something is still missing. |
Now start the containers. You can start all containers (including Kibana) or all containers except Kibana.
Go to folder api-mgmt/single-host-setup (folder that contains the file docker-compose.yml).
To start all containers except Kibana, use:
docker-compose up ui gateway |
or
docker-compose up -d ui gateway |
Starting all services (previous step) may take some time. If the UI is not available yet, just wait a moment. |
Open the URL of your API Management, e.g. https://api.acme-corp.com:8443 and log in with the standard administration user, which is admin/admin.
Upload the initial configuration of API Management.
To do this, go to Administration > Export/Import and import file api-mgmt/configs/bootstrap/apiman-default-config.json from api-mgmt-<VERSION>.zip. If you did not transfer the file to your client in step1, you can download the file here.
Test the connection between UI and gateway.
To do this, go to Administration > Manage Gateways and click on the name of the gateway. Then, click Test Gateway.
A technical user (gateway/gateway) connects the UI of API Management with the gateway. It is highly recommended to change the default passwords for both, the admin user and the gateway user. Both passwords can be changed in Keycloak. |
Kibana
If you want to use Kibana for your reports on API Management metrics, you may want to proceed with Setting-up Kibana.
However, as Kibana get be setup any time after having installed API Management, we recommend to configure API Management first and record some API data, before using Kibana. |
