docker: Error response from daemon: invalid volume specification - docker

Question

I'm currently following this tutorial to run a model on Docker that was built using the Google Cloud AutoML Vision:
https://cloud.google.com/vision/automl/docs/containers-gcs-tutorial
I'm having trouble running the container, specifically running this command:
sudo docker run --rm --name ${CONTAINER_NAME} -p ${PORT}:8501 -v ${YOUR_MODEL_PATH}:/tmp/mounted_model/0001 -t ${CPU_DOCKER_GCR_PATH}
I have my environment variables set up right (did an echo $<env_var>). I do not have a /tmp/mounted_model/0001 directory on my local system. My model path is configured to be the model location on the cloud storage.

Answer 1

${YOUR_MODEL_PATH} must be a directory on the host on which you're running the container.
Your question suggests that you're using the Cloud Storage bucket path but you cannot do this.
Reviewing the tutorial, I think the instructions are confusing.
You are told to:
gsutil cp \
${YOUR_MODEL_PATH} \
${YOUR_LOCAL_MODEL_PATH}/saved_model.pb
So, your command should probably be:
sudo docker run \
--rm \
--interactive --tty \
--name=${CONTAINER_NAME} \
--publish=${PORT}:8501 \
--volume=${YOUR_LOCAL_MODEL_PATH}:/tmp/mounted_model/0001 \
${CPU_DOCKER_GCR_PATH}
NB I added --interactive --tty to make debugging easier; it's optional
NB ${YOUR_LOCAL_MODEL_PATH} not ${YOUR_MODEL_PATH}
NB The command should not be -t ${CPU_DOCKER_GCR_PATH} omit the -t
I've not run through this tutorial.
