Berikut ini akan dijelaskan cara untuk menginstall Docker bukan Podman di Fedora 34.
1. Install plugin DNF
Pertama install plugin DNF dnf-plugins-core
sudo dnf -y install dnf-plugins-core
2. Tambahkan repository Docker dari docker.com
sudo dnf config-manager --add-repo https://download.docker.com/linux/fedora/docker-ce.repo
3. Install Docker
sudo dnf -y install docker-ce docker-ce-cli containerd.io
Tambahkan user anda kedalam group docker, agar bisa menjalankan docker dengan user biasa
sudo usermod -aG docker $USER
pastikan user anda sudah masuk kedalam group docker
$ id jaranguda uid=1000(jaranguda) gid=1000(jaranguda) groups=1000(jaranguda),10(wheel),973(vboxusers),970(docker)
Jalankan service docker
sudo systemctl enable --now docker
Coba jalankan perintah docker
docker pull alpine:latest
bila anda mendapati error
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.24/images/create?fromImage=alpine&tag=latest: dial unix /var/run/docker.sock: connect: permission denied
Periksa permission socket docker
ls -l /var/run/docker.sock # output srw-rw---- 1 root root 0 Jul 5 11:34 /var/run/docker.sock
karena kita baru menambahkan user kedalam group docker, perubahan tersebut belum terdeteksi. Reboot atau logoff lalu jalankan kembali perintah docker diatas.
Kita coba mendownload images dari Docker HUB, lalu menjalankan perintah sederhana
$ docker run -it alpine:latest ping -c5 google.com PING google.com (74.125.24.102): 56 data bytes 64 bytes from 74.125.24.102: seq=0 ttl=105 time=18.725 ms 64 bytes from 74.125.24.102: seq=1 ttl=105 time=17.621 ms 64 bytes from 74.125.24.102: seq=2 ttl=105 time=17.589 ms 64 bytes from 74.125.24.102: seq=3 ttl=105 time=17.359 ms 64 bytes from 74.125.24.102: seq=4 ttl=105 time=17.297 ms
