Boot2Docker到Google Compute Engine VM：保存Docker容器

Question

I am running Boot2Docker v1.0.1 on Windows, and wish to fire up a Docker container I have created on a Google Compute Engine VM.

In order to do so, I need to save the container and upload it to Google Cloud Storage. I issue the following command:

docker save --output=mycontainer.tar mycontainer:latest

The command completes without error. However, I cannot find the rce_env.tar file anywhere on my hard drive.

Does anyone have any experience with this? If not, is there a better way to run containers on GCE VM's?

Answer 1

You can run google/docker-registry locally to push your container images to GCS.

docker run -ti --name gcloud-config google/cloud-sdk \
  gcloud auth login
docker run -ti --volumes-from gcloud-config google/cloud-sdk \
  gcloud config set project <project>
docker run -d -e GCS_BUCKET=bucketname -p 5000:5000 \
  --volumes-from gcloud-config google/docker-registry
docker tag imagename localhost:5000/imagename
docker push localhost:5000/imagename

And then run it on GCE to pull your containers from GCS.

docker run -d -e GCS_BUCKET=bucketname -p 5000:5000 google/docker-registry
docker run localhost:5000/imagename

I understand that you are using boot2docker on windows.

On a similar setup, using OSX and boot2docker 1.1.0 , the following works:

docker save --output mycontainer.tar mycontainer:latest

As also does redirecting standard output:

docker save mycontainer:latest > mycontainer.tar

Answer 3

GCE now allows to store docker images for your projects using the gcloud command.

you can now run $ gcloud preview docker push gcr.io/YOUR-PROJECT/IMAGE-NAME
