Welcome to the docker-vagrant wiki! ✏️ 📚

The aim of this wiki is show the most common tasks used on Docker 🐳.

All you need, is running Vagrant with Docker and Internet connection. Another way to get Docker, is Play With Docker.

⚠️ You need a Docker Hub account to be able to login, however, if you don't want to create a Docker Hub account with your private email, you can use a temporary email to do the practice.

If everything was fine, login via SSH:

vagrant ssh

Internal & External IP

💡 Throughout wiki, there are examples in which we expose ports outside. We can use localhost or a Web browser (Firefox, Google Chrome, Edge). So that, we need to know what IPs are assigned to VM.

  • Internal
vagrant@ubuntu-xenial:~$ ifconfig enp0s3
enp0s3    Link encap:Ethernet  HWaddr 02:af:57:b2:64:eb  
          inet addr:10.0.2.15  Bcast:10.0.2.255  Mask:255.255.255.0
          inet6 addr: fe80::af:57ff:feb2:64eb/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:351150 errors:0 dropped:0 overruns:0 frame:0
          TX packets:31852 errors:0 dropped:0 overruns:0 carrier:0

          RX bytes:339109166 (339.1 MB)  TX bytes:2085246 (2.0 MB)
  • External
vagrant@ubuntu-xenial:~$ ifconfig enp0s8
