### Instalasi
Pada snap package `docker` sudah tersedia dan dapat langsung diinstal

```bash
$ sudo snap install docker
```

setelah proses instalasi selesai, program `docker` langsung dapat digunakan.

```bash
$ docker --version
```

akan memunculkan versi docker yang terinstall. 

### Akses Root
Akses docker pada saat instalasi awal akan membutuhkan akses root, misal ketika menjalankan `hello-world` tanpa `sudo`

```bash
$ docker run hello-world
```

akan memunculkan error berikut

```bash
docker: permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Head "http://%2Fvar%2Frun%2Fdocker.sock/_ping": dial unix /var/run/docker.sock: connect: permission denied.
See 'docker run --help'.
```

namun jika dijalankan menggunakan perintah `sudo` program akan berjalan dengan baik

```bash
$ sudo docker run hello-world
```

output:
```bash
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/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

Bagi saya sendiri akses docker menggunakan root tidak terlalu masalah. Untuk kalian yang ingin menggunakan docker tanpa akses root, kalian bisa cari di google ada banyak artikel yang bisa kalian baca.

Install docker menggunakan packager snap di OS Ubuntu Server 24.04 LTS. Docker yang diinstal melalui snap membutuhkan akses root agar dapat menjalankan docker image.
