I. 설치
1. 설치(ubuntu 14.04 에서).
아래 커맨드로, docker repository를 위한 pgp key를 등록한다.
# apt-key adv --keyserver hkp://pgp.mit.edu:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --homedir /tmp/tmp.fq7Qgn6cd8 --no-auto-check-trustdb --trust-model always --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver hkp://pgp.mit.edu:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D gpg: requesting key 2C52609D from hkp server pgp.mit.edu gpg: key 2C52609D: public key "Docker Release Tool (releasedocker) <docker@docker.com>" imported gpg: Total number processed: 1 gpg: imported: 1 (RSA: 1)
docker repository를 등록한다. /etc/apt/sources.list.d/docker.list 화일을(없으면 만들고) 아래와 같이 편집한다. os version이 ubuntu14.04이므로 trusty repository를 등록.
#vi /etc/apt/sources.list.d/docker.list # Ubuntu Trusty deb https://apt.dockerproject.org/repo ubuntu-trusty main
ubuntu 14.04 이전 버전에서는 설치 시 커널을 업그레이드 해 주어야 하지만, 여기서는 14.04 이기 때문에, 커널 업그레이드는 필요 하지 않다.
