| 5 | Install Docker
|
| 6 | ===============
|
| 7 |
|
| 8 | Make sure curl is installed on the Ubuntu VM:
|
| 9 |
|
| 10 | .. code-block:: bash
|
| 11 |
|
| 12 | sudo apt update
|
| 13 | sudo apt install curl
|
| 14 |
|
| 15 | If you are behind a corporate firewall (replace "proxyhost:port" with your actual proxy information)
|
| 16 | https_proxy="https://*proxyhost:port*" curl -fsSL https://apt.dockerproject.org/gpg | sudo apt-key add -
|
| 17 |
|
| 18 | Otherwise:
|
| 19 | curl -fsSL https://apt.dockerproject.org/gpg | sudo apt-key add -
|
| 20 | Expected Response:
|
| 21 | OK
|
| 22 | Add the docker package repository:
|
| 23 | sudo apt-add-repository "deb https://apt.dockerproject.org/repo ubuntu-xenial main"
|
| 24 |
|
| 25 | Install packages:
|
| 26 |
|
| 27 | .. code-block:: bash
|
| 28 |
|
| 29 | sudo apt update
|
| 30 | sudo apt-cache policy docker-engine
|
| 31 | sudo apt install docker-engine
|
| 32 | sudo apt install docker-compose
|
| 33 |
|
| 34 | If you are behind a corporate firewall, you will need to configure proxy settings for docker so that images may be obtained from internet repositories. In the commands shown here, replace *"proxyhost:port"*, *"yourdomain1.com"*, and *"yourdomain2.com"* with appropriate values.
|
| 35 |
|
| 36 | Make the docker configuration directory:
|
| 37 |
|
| 38 | .. code-block:: bash
|
| 39 |
|
| 40 | sudo mkdir -p /etc/systemd/system/docker.service.d
|
| 41 |
|
| 42 | Edit (create) this file:
|
| 43 |
|
| 44 | .. code-block:: bash
|
| 45 |
|
| 46 | sudo vi /etc/systemd/system/docker.service.d/http-proxy.conf
|
| 47 |
|
| 48 | Add these lines:
|
| 49 |
|
| 50 | [Service]
|
| 51 |
|
| 52 | Environment="HTTP_PROXY=https://*proxyhost:port*"
|
| 53 |
|
| 54 | Environment="HTTPS_PROXY=https://*proxyhost:port*"
|
| 55 |
|
| 56 | Environment="NO_PROXY=localhost,127.0.0.1,.yourdomain1.com,.yourdomain2.com"
|
| 57 |
|
| 58 | Restart docker:
|
| 59 |
|
| 60 | .. code-block:: bash
|
| 61 |
|
| 62 | sudo systemctl daemon-reload
|
| 63 | sudo systemctl restart docker
|
| 64 |
|
| 65 | Add yourself to the docker user group (replace "userid" with your user ID):
|
| 66 |
|
| 67 | .. code-block:: bash
|
| 68 |
|
| 69 | sudo usermod -a -G docker *userid*
|
| 70 |
|
| 71 | Log out and log back in so that the user group change will takeeffect.
|
| 72 |
|
| 73 | Verify that you can connect to docker as yourself (i.e. not as root):
|
| 74 |
|
| 75 | .. code-block:: bash
|
| 76 |
|
| 77 | docker ps
|
| 78 |
|
| 79 | Verify that you can download and run the hello-world container
|
| 80 |
|
| 81 | .. code-block:: bash
|
| 82 |
|
| 83 | docker run hello-world
|
