First, up and run your container as above. It will be waiting for two plexdrive configuration files to be ready. You can create those files using built-in script by

docker-compose exec <service_name> plexdrive_setup

Once you finish typing your API token, shell stops responding. No worries, it is expected. Simply escape by Ctrl+C, and go to /config. You will find two json files generated. Container running in background will proceed to execute mounting command for plexdrive.

Once google drive contents are mounted with plexdrive, the container will mount decrypted remote and local directories then mount a merged directory which is accessible at ${DATA_DIR}/plexdrive/data.

plexdrive mount

Here is the internal command for plexdrive mount.

plexdrive mount /cloud \
    -c /config/ \
    --cache-file=/cache/cache.bolt \
    --uid=${PUID:-911} \
    --gid=${PGID:-911} \
    --umask=022 \
    -o allow_other \
    ${PLEXDRIVE_OPTS}

Variables with capital letters are only configurable by the container environment variable.

After plexdrive mounts /cloud, encfs is used to create decrypted mounts of /cloud and /local

ENCFS6_CONFIG="/encfs.xml" /usr/bin/encfs -v --extpass="/bin/cat /encfspass" /cloud /data-decrypted
ENCFS6_CONFIG="/encfs.xml" /usr/bin/encfs -v --extpass="/bin/cat /encfspass" /local /local-decrypted

unionfs \
    -o uid=${PUID:-911},gid=${PGID:-911},umask=022,allow_other \
    -o ${UFS_USER_OPTS} \
    /local-decrypted=RW:/data-decrypted=RO /data

where a default value of UFS_USER_OPTS is

UFS_USER_OPTS="cow,direct_io,nonempty,auto_cache,sync_read"
