Installing Docker for Containerized UDFs
The installation owner needs to be part of the Docker group to download and install containerized services (such as UDF, Spark-provider, and TensorFlow microservice) during the installation process.
1. To check the list of groups, issue the following command.
>groups
2. To add the installation owner (for example, Ingres) as part of the Docker group, issue the following command as a root user.
>usermod -a -G docker ingres
Note: The installation owner must be part of the Docker group.
3. To verify if the user is part of the Docker group, issue the following command.
>grep docker /etc/group
