2. docker
官方文档：https://docs.docker.com/install/linux/docker-ce/ubuntu/
(1) 安装依赖：
sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
gnupg-agent \
software-properties-common
(2) Manage Docker as a non-root user
The Docker daemon binds to a Unix socket instead of a TCP port. By default that Unix socket is owned by the user root and other users can only access it using sudo. The Docker daemon always runs as the root user.
If you don’t want to preface the docker command with sudo, create a Unix group called docker and add users to it. When the Docker daemon starts, it creates a Unix socket accessible by members of the docker group.
To create the docker group and add your user:
Create the docker group.
$ sudo groupadd docker
Add your user to the docker group.
$ sudo usermod -aG docker $USER
Log out and log back in so that your group membership is re-evaluated.
If testing on a virtual machine, it may be necessary to restart the virtual machine for changes to take effect.
On a desktop Linux environment such as X Windows, log out of your session completely and then log back in.
Verify that you can run docker commands without sudo.
$ docker run hello-world
This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits.
(3)检查
检查一下创建是否有效
cat /etc/group
退出当前用户登陆状态，然后重新登录，以便让权限生效,或重启docker-daemon
sudo systemctl restart docker
3. npm
sudo apt-get install npm
无可避免会安装python2.7的依赖
