Custom truststore

This section covers configuring a custom truststore for the Token Server.

It is possible to run the Token Server container with a custom truststore. The truststore is used to define the certificates that the Token Server can trust when creating SSL connections to external systems / a database.

This section is divided into the following subsections:

Create folder

Before we can use the truststore, we need a folder to store the truststore file. This folder will be mounted to the Onegini Token Server container later on.

mkdir -p /opt/onegini/data/truststore

If you are using SELinux, you need to give Docker access to this folder. To do this you can use the following command:

chcon -Rt svirt_sandbox_file_t /opt/onegini/data/truststore

Generate truststore

Perform the following command to generate the truststore.

keytool -genkey -alias tokenserver -keyalg RSA -keystore truststore.jks

Once prompted, enter the information required to generate a CSR.


Now we can copy the truststore to the folder we created.

cp truststore.jks /opt/onegini/data/truststore/truststore.jks

Grant access

Before we can use the truststore in the Onegini Token Server container we need to give the onegini user access to the truststore.

chown -R onegini:onegini /opt/onegini/data/truststore

Start container

Now add the following line to the docker-compose.yml

    - "/opt/onegini/data/truststore:/opt/data/truststore"

and edit the following Docker Compose environment variables:


Restart the container with docker-compose

Import certificates

If the Onegini Token Server needs to connect to a server with SSL certificates. You need to trust this server before the Onegini Token Server can make a connection. If you do not import this SSL certificates you will get a execption.

keytool -import -alias apple-push -file apple-push.crt -keystore truststore.jks
