Add project DNS entry on Linux

******************************

|
|
On Linux, custom DNS entries can be added to the ``/etc/hosts`` and will take precedence over the
|
||
|
|
same entries provided by any DNS server.

Assumption
|
||
|
|
==========
|
||
|
|
|
||
|
|
In order to better illustrate the process, we are going to use two projects as an example.
|
||
|
|
See the following table for project directories and :ref:`env_tld_suffix`.
|
||
|
|
|
||
|
|
+-------------------+------------+--------------------------+-----------------------+
|
||
|
|
| Project directory | TLD_SUFFIX | Project URL | Required DNS name |
|
||
|
|
+===================+============+==========================+=======================+
|
||
|
|
| project-1 | ``loc`` | http://project-1.loc | ``project-1.loc`` |
|
||
|
|
+-------------------+------------+--------------------------+-----------------------+
|
||
|
|
| www.project-1 | ``loc`` | http://www.project-1.loc | ``www.project-1.loc`` |

Step by step
|
||
|
|
------------
|
||
|
|
|
||
|
|
When using Docker on Linux you can use ``127.0.0.1`` for the IP address.
|
||
|
|
|
||
|
|
1. Open ``/etc/hosts`` with root privileges or via ``sudo`` with your favorite editor
|
||
|
|
|
||
|
|
.. code-block:: bash
|
||
|
|
|
||
|
|
host> sudo vi /etc/hosts
|
||
|
|
|
||
|
|
2. Add DNS records for the above listed examples:
|
||
|
|
|
||
|
|
.. code-block:: bash
|
||
|
|
:caption: /etc/hosts
|
||
|
|
|
||
|
|
127.0.0.1 project-1.loc
|
||
|
|
127.0.0.1 www.project-1.loc
|
||
|
|
|
||
|
|
3. Safe the file and verify the DNS entries with the ``ping`` command
|
||
|
|
|
||
|
|
.. code-block:: bash
|
||
|
|
|
||
|
|
host> ping -c1 project-1.loc
|
||
|
|
|
||
|
|
PING project-1.loc (127.0.0.1) 56(84) bytes of data.
|
||
|
|
64 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.066 ms
|
||
|
|
|
||
|
|
.. code-block:: bash
|
||
|
|
|
||
|
|
host> ping -c1 www.project-1.loc
|
||
|
|
|
||
|
|
PING www.project-1.loc (127.0.0.1) 56(84) bytes of data.
|
||
|
|
64 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.066 ms
