Redis – Using tmpfs in MacOS

I am new to Docker and trying to run a container in Docker on my macOS so it doesn’t run on persistent memory. On my Linux machine, I figured I can execute it this way:

sudo docker run -dit --name minemeld --restart unless-stopped --tmpfs /run -v minemeld-local:/opt/minemeld/local -v minemeld-logs:/opt/minemeld/log  -p 443:443 -p 80:80 paloaltonetworks/minemeld

However, though macOS takes this command, the container doesn’t run as intended. Specifically, I see the following messages:

Regenarating CA bundle
2020-01-10T18:54:01 (232)cacert_merge.main INFO: config: {'cafile': ['/opt/minemeld/local/certs/site/'], 'dst': '/opt/minemeld/local/certs/bundle.crt', 'config': '/opt/minemeld/local/certs/cacert-merge-config.yml', 'no_merge_certifi': False}

I have created a RAM disk for now called “DockerDisk:

SJCMAC:~ jaydee$ ls /Volumes/
DockerDisk  Macintosh HD    Recovery

How do I run my docker container to point to this volume? In other words, what exactly do I change from the syntax above to achieve this on macOS? I’d appreciate any pointers.
