About Volumes and Volume Validation
In addition to the database connectivity and integrity checks, My webMethods Server also performs volume validation when you start a container from a My webMethods Server Docker image. Volume validation checks ensure the following:
The specified named volumes and mounted host directories exist, and the specified paths are real paths
The specified named volumes and host directories have appropriate read/write permissions
Volumes and host directories mapped to directories that support both read and write modes contain only compatible data (if any). Such directories are
MWS/volumes/data and
MWS/volumes/logs. Data is compatible and can be reused when generated by a
My webMethods Server container that has the same release version, the same or greater fix version, and the same instance, cluster, and node IDs.
If any of the volume validation checks fails, the container exits. Logs are available on the console and in the default (anonymous) Docker volume, or the named volume mapped to it (if available). For more information about volume and data sharing between containers, see
Managing Assets and Data in My webMethods Server Containers.
For more information about using volumes and mounted host directories, see the Docker documentation.
