问题
I need my image to start with this command:
docker run -it --rm --security-opt seccomp=./chrome.json <image_id>
I'm deploying it to Google Compute Engine: https://cloud.google.com/compute/docs/containers/deploying-containers
As far as I understand, I can't specify arguments there, so Google Cloud starts it with just docker run command.
How do I pass these arguments? Maybe I can specify those args in Dockerfile somehow?
回答1:
When you use the feature to deploy container directly on Compute Engine, you are limited to the definition of
- Entry point
- Args to pass at the entry point
- Environment variables
That's all, you can't add additional/custom params.
One solution is, instead of using the built in feature, to use the container-optimized OS (COS) on your Compute Engine and to create a startup script to download and run the container with the docker args that you want
METADATA=http://metadata.google.internal/computeMetadata/v1
SVC_ACCT=$METADATA/instance/service-accounts/default
ACCESS_TOKEN=$(curl -H 'Metadata-Flavor: Google' $SVC_ACCT/token | cut -d'"' -f 4)
docker login -u oauth2accesstoken -p $ACCESS_TOKEN https://gcr.io
docker run … gcr.io/your-project/your-image
On the latest line, you can customize the run param in your startup script.
So now, for the update, you have to update the startup script and to reset your VM (or to create a new Compute Engine with COS and the new startup script; and to delete the previous one).
It's matter of tradeoff between the convenience of a built in feature and the customization capacity.
