ubuntu1404安装dockerce

1. 升级linux kernel

2. 手动下载deb包进行安装

Install from a package

If you can't use Docker's apt repository to install Docker Engine, you can download the deb file for your release and install it manually. You need to download a new file each time you want to upgrade Docker Engine.

Go to https://download.docker.com/linux/ubuntu/dists/.
Select your Ubuntu version in the list.
Go to pool/stable/ and select the applicable architecture (amd64, armhf, arm64, or s390x).
Download the following deb files for the Docker Engine, CLI, containerd, and Docker Compose packages:
- containerd.io_<version>_<arch>.deb
- docker-ce_<version>_<arch>.deb
- docker-ce-cli_<version>_<arch>.deb
- docker-buildx-plugin_<version>_<arch>.deb
- docker-compose-plugin_<version>_<arch>.deb
Install the .deb packages. Update the paths in the following example to where you downloaded the Docker packages.

The Docker daemon starts automatically.
Verify that the Docker Engine installation is successful by running the hello-world image.

$ sudo service docker start
$ sudo docker run hello-world
```
This command downloads a test image and runs it in a container. When the container runs, it prints a confirmation message and exits.
