Use Docker on the Cloud

Launch Instance with Docker​

Right now if you want to use Docker on the cloud, you need to select docker container before launching the instance. img.png

Install Docker​

apt update
apt-get install -y \
apt-transport-https \
  ca-certificates \
  curl \
  gnupg-agent \
  software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
add-apt-repository   "deb [arch=amd64] https://download.docker.com/linux/ubuntu/ \
  $(lsb_release -cs) \
  stable"
apt-get update && apt-get install -y docker-ce-cli

Verify Docker Installation​

(base) root@notebook-1a62dca9-92b6-11ef-b741-c663643c702b-0:~# docker ps
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES

Notes​

  • You can build your own Docker image on cloud and upload it to the cloud. 
# first upload your image using scp or sftp to the instance
scp -P instance_port </path/to/local/file> root@instance_ip:<destination path>
# then load the image to docker
docker load -i <destination path>(e.g. /root/your_image.tar.gz)
  • docker data is not persistent if the instance is stopped or terminated. Please store your images in remote storage if needed.
docker save -o <destination path> <image_name>
cp <destination path> /root/dataDisk/
  • You can directly mount the GPU from the instance into the container when using docker run without needing to specify the --gpus parameter; the GPU is shared between the instance and the docker container.
  • Currently, only the /root path (including subpaths like /root/xxx) on the instance can be mounted into the container, e.g. docker run -v /root:/root. Other paths are not supported for mounting at this time.
  • Privileged mode is also not supported for now.
  • The Docker will not be enabled when starting up with CPU instances.
