sebelumnya saya menginstall docker ini di ubuntu 16.04 yang saya deploy diatas (OPENSTACK), hasilnya cukup bagus belum ada masalah

untuk menginstall docker di ubuntu ini sebenarnya cukup sederhana, seperti berikut dengan login mengunakan root

update dan upgrade ubuntu

apt update && apt upgrade

1	apt update && apt upgrade

install apt transport https dan ca certificate

apt install apt-transport-https ca-certificates

1	apt install apt-transport-https ca-certificates

tambahkan GPG key baru untuk repositori docker

apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 \
            --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

1 2	apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 \ --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

tamhkan repositori untuk docker (ubuntu xenial)

echo "deb https://apt.dockerproject.org/repo ubuntu-xenial main" | tee /etc/apt/sources.list.d/docker.list

1	echo "deb https://apt.dockerproject.org/repo ubuntu-xenial main" \| tee /etc/apt/sources.list.d/docker.list

kemudian update kembali

apt update

1	apt update

kemudian verifikasi repository yang sudah kita update sebelumnya

kemudian install kernel tambahan

apt-get install linux-image-extra-$(uname -r) linux-image-extra-virtual

1	apt-get install linux-image-extra-$(uname -r) linux-image-extra-virtual

kemudian install docker-engine

root@docker1-ubuntu:/home/ubuntu# apt install docker-engine

1	root@docker1-ubuntu:/home/ubuntu# apt install docker-engine

kemudian restart / start service docker

root@docker1-ubuntu:/home/ubuntu# systemctl restart docker
root@docker1-ubuntu:/home/ubuntu# systemctl status docker

kemudian kita coba untuk testing menjalankan image hello-world

root@docker1-ubuntu:/home/ubuntu# docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
c04b14da8d14: Pull complete 
Digest: sha256:0256e8a36e2070f7bf2d0b0763dbabdd67798512411de4cdcf9431a1feb60fd9
Status: Downloaded newer image for hello-world:latest

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.
 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

okee sudah berhasil, untuk installasi docker sebenarnya sudah selesai sampai sini, untuk selanjutnya kita akan coba menjalankan image docker yang lainnya dan memanag networknya

kemudian saya akan membuat user alan pada docker

adduser alan

1	adduser alan

kemudian isikan password sesuai kebutuhan anda, kemudian beri akses user non-root pada docker

root@docker1-ubuntu:/home/ubuntu# usermod -aG docker alan

1	root@docker1-ubuntu:/home/ubuntu# usermod -aG docker alan

perintah diatas berfungsi untuk memberikan akses kepada user alan supaya dapat mengakses command docker yang secara default hanya bisa diakses oleh user root.

Enable Memory dan SWAP

by default VM docker tidak bisa mengunakan swap pada host, itu kita bisa ketahui ketika menjalankan command docker info
