Container Containerd

Containerd 설치 및 환경 세팅하기

containerd만 단독으로 설치 했을 경우 CRI의 기능만 제공하며, docker처럼 기능을 사용하기 위해선 플러그인 설치가 필요

  1. containerd 설치

    for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo dnf remove $pkg -y; done
dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
dnf install -y containerd.io
containerd config default | sudo tee /etc/containerd/config.toml

  2. containerd 디렉토리 설정(선택)

    ### containerd root 디렉토리 외에 data 디렉토리에서 동작하도록 설정
sed -i 's|^root = .*|root = "/data/container/containerd"|' /etc/containerd/config.toml
sed -i 's|^state = .*|state = "/data/container/containerd-state"|' /etc/containerd/config.toml
mkdir -p /data/container/containerd
mkdir -p /data/container/containerd-state
mkdir -p /data/container/nerdctl
echo 'export NERDCTL_DATA_ROOT=/data/container/nerdctl' >> ~/.bashrc
source ~/.bashrc

  3. nerdctl 설치

    • 도커 명령어처럼 containerd를 관리하기 위한 툴
      • ex) nerdctl ps -a, nerdctl images

tar Cxzvvf /usr/bin nerdctl-0.17.0-linux-amd64.tar.gz
echo "source <(nerdctl completion bash)" >> ~/.bashrc

  4. CNI 설치
