Installasi Docker di OpenSUSE -  Setelah kita mengenal tentang Docker dan Container pada postingan sebelumnya, Kali ini kita akan melakukan Installasi Docker tersebut. Saya telah membuat postingan tentang Pengenalan Docker secara terpisah. Dalam installasi disini saya menggunakan OpenSUSE Leap15.2. Jika kalian belum baca postingan pengenalan tentang Docker di blog ini, Kalian bisa klik link dibawah

Oke kita langsung saja masuk ke tahap Installasi nya.

  • Perbarui informasi depedency dari repository anda.
tegar@localhost:~> sudo zypper up
  • Install Docker.
tegar@localhost:~> sudo zypper in docker -y

  • Aktifkan service docker
tegar@localhost:~> sudo systemctl enable docker 
[sudo] password for root: 
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.
tegar@localhost:~> sudo systemctl start docker
  • Verifikasi Bahwa Docker telah active
tegar@localhost:~> docker --version
Docker version 19.03.11, build 42e35e61f352
tegar@localhost:~> systemctl status docker

Images pada docker 

Kita bisa menggunakan dan menginstall image yang telah tersedia pada docker, Untuk melihat image apa saja yang tersedia kalian bisa main langsung ke https://hub.docker.com/. Pun kita dapat membuat image kita sendiri kemudian di deploy ke docker.

Disini kita akan coba pull image hello-world yaitu image dari docker yang telah disediakan pada library docker, Kita bisa take image tersebut dengan perintah pull.

tegar@localhost:~> sudo docker pull hello-world
Using default tag: latest
latest: Pulling from library/hello-world
0e03bdcc26d7: Pull complete 
Digest: sha256:8c5aeeb6a5f3ba4883347d3747a7249f491766ca1caa47e5da5dfcf6b9b717c0
Status: Downloaded newer image for hello-world:latest
docker.io/library/hello-world:latest
tegar@localhost:~>

Running Image docker

Selanjutnya kita coba jalankan image hello-world yang telah kita download sebelumnya,
tegar@localhost:~> sudo docker run hello-world

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Share images, automate workflows, and more with a free Docker ID:

 https://docs.docker.com/get-started/

tegar@localhost:~>

Sampai sini image hello-world tersebut telah berhasil kita download dan kita jalankan.

Selanjutnya kita dapat melakukan pengecekan image dan container yang kita miliki dengan perintah berikut.

tegar@localhost:~> sudo docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
hello-world         latest              bf756fb1ae65        9 months ago        13.3kB
tegar@localhost:~> sudo docker container ls -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                     PORTS               NAMES
366c28a57e14        hello-world         "/hello"            5 minutes ago       Exited (0) 5 minutes ago                       frosty_aryabhata
tegar@localhost:~>

Dapat dilihat pada docker images terdapat image hello-world yang telah kita pull sebelumnya.

Sampai sini dulu postingan kali ini, Semoga next nya kita bisa lebih jauh belajar manajemen container di blog ini.

Ciaoww
