Hai semuanya, di materi kali ini kita akan membahas Install docker-machine di OS Linux khususnya Ubuntu Desktop. Materi yang dibahas diantaranya:

  1. Install docker-machine binary
  2. Install VirtualBox as backend
  3. Create and run a Docker host using VirtualBox provider
  4. Troubleshooting

Ok langsung aja kita bahas materi yang pertama

Install docker-machine binary

If you want only Docker Machine, you can install the Machine binaries directly by following the instructions in the next section.

You can find the latest versions of the binaries are on the docker/machine release page on GitHub. To install you need run this command:

Jika di jalankan outputnya seperti berikut:

➜  ~ export DOCKER_MACHINE_VERSION=v0.16.2

➜  ~ curl -L https://github.com/docker/machine/releases/download/$DOCKER_MACHINE_VERSION/docker-machine-`uname -s`-`uname -m` >/tmp/docker-machine &&
    chmod +x /tmp/docker-machine &&
    sudo cp /tmp/docker-machine /usr/local/bin/docker-machine

➜  ~ docker-machine -v
docker-machine version 0.16.2, build bd45ab13

Install VirtualBox as backend

Docker machine membutuhkan backend atau driver untuk virtualization, Ada beberapa driver yang kita bisa gunakan yaitu

  1. Virtualbox (virtualbox)
  2. VMware Workstation (vmware)

Yang telah saya test dan juga work well yaitu virtualbox jadi kita akan menggunakan VirtualBox ya sebagai drivernya. Untuk menginstall Virtualbox kita bisa Download binary dari official dokumentasi Virtualbox kemudian kita install sesuai dengan platform. Karena saya menggunakan Ubuntu Desktop 21.04 maka kita bisa menggunakan perintah seperti berikut:

dpkg -i virtualbox-xxx.xxx_Ubuntu_eoan_xxxx.deb

Setelah kita install kita perlu make sure, Virtualbox bisa menjalankan vm. Silahkan temen-temen buat saja 1 vm pake os Linux distronya boleh bebas. Jika ada problem seperti berikut:

Error creating machine: Error in driver during machine creation: Error setting up host only network on machine start: /usr/local/bin/VBoxManage hostonlyif ipconfig vboxnet0 --ip 192.168.99.1 --netmask 255.255.255.0 failed:

Solusinya coba

  1. find all the “host-only ethernet adapters” with VBoxManage list hostonlyifs
  2. Remove the orphaned ones with VBoxManage hostonlyif remove <networkName>
  3. Create a vbox folder in the etc directory with sudo mkdir /etc/vbox
  4. Create a file networks.conf in the vbox folder with sudo touch /etc/vbox/networks.conf
  5. Write inside file network.conf with * 0.0.0.0/0 ::/0

Create and run a Docker host using VirtualBox provider

Machine lets you create Docker hosts on your computer, on cloud providers, and inside your own data center. It creates servers, installs Docker on them, then configures the Docker client to talk to them.

Jika dijalankan maka hasilnya seperti berikut:

➜  ~ docker-machine create -d virtualbox --virtualbox-no-vtx-check default

To see how to connect your Docker Client to the Docker Engine running on this virtual machine, run: docker-machine env default

➜  ~ docker-machine ls

Dengan seperti itu kita sudah bisa membuat docker server yang jalan di atas Virtualbox dengan ip 192.168.99.101

Troubleshooting

Docker Machine tries to do the right thing in a variety of scenarios but sometimes things do not go according to plan. Here is a quick troubleshooting guide which may help you to resolve of the issues you may be seeing.

  1. docker-machine hangs, A common issue with Docker Machine is that it will hang when attempting to start up the virtual machine. Since starting the machine is part of the create process, create is often where these types of errors show up. A hang could be due to a variety of factors, but the most common suspect is networking. Consider the following:
    1. Are you using a VPN? If so, try disconnecting and see if creation will succeed without the VPN. Some VPN software aggressively controls routes and you may need to manually add the route.
    2. Are you connected to a proxy server, corporate or otherwise? If so, take a look at the --no-proxy flag for env and at setting environment variables for the created Docker Engine.
    3. Are there a lot of host-only interfaces listed by the command VBoxManage list hostonlyifs? If so, this has sometimes been known to cause bugs. Consider removing the ones you are not using (VBoxManage hostonlyif remove name) and trying machine creation again.
  2. Machine creation errors out before finishing, If you see messages such as exit status 1 creating machines with VirtualBox, this frequently indicates that there is an issue with VirtualBox itself.
