1. Uninstall old version
$ sudo apt-get remove docker docker-engine docker.io containerd runc

2. Update the apt package index and install packages to allow apt to use a repository over HTTPS:
$ sudo apt-get update
$ sudo apt-get install \
 apt-transport-https \
 ca-certificates \
 curl \
 gnupg-agent \
 software-properties-common

3. Add Docker’s official GPG key:
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

4. Verify that you now have the key with the fingerprint 9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88, by searching for the last 8 characters of the fingerprint.

$ sudo apt-key fingerprint 0EBFCD88

pub   rsa4096 2017-02-22 [SCEA]
      9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
uid           [ unknown] Docker Release (CE deb) <docker@docker.com>
sub   rsa4096 2017-02-22 [S]

5. Use the following command to set up the stable repository. 

$ sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

6.
 $ sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

7. Update the apt package index, and install the latest version of Docker Engine and containerd, or go to the next step to install a specific version:
 $ sudo apt-get update
 $ sudo apt-get install docker-ce docker-ce-cli containerd.io

8. To install a specific version of Docker Engine, list the available versions in the repo, then select and install:
a. List the versions available in your repo:
$ apt-cache madison docker-ce

$ docker run --name lionel-yocto-build -it -v $(pwd):/yocto crops/yocto:ubuntu-18.04-builder

했는데 안되네. 어떻게 쓰는건지 모르겠다.











다른 방법으로 다시 도전.
이번엔 이미지를 만들어서 해보자

docker build --file dockerfile_bionic --tag ubuntu_bionic .


docker run -v <host directory>:<container directory> -it ubuntu_bionic

실행.

다음에 다시 붙을 때
