Accessing the web server

~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
By default our docker-compose config exposes the web-server on port 80 of localhost.

|
||||
We use olympia.dev as the default hostname to access your container server (e.g. for
|

We use ``olympia.dev`` as the default hostname to access your container server (e.g. for
|
||||
Firefox Accounts). To be able access the development environment using ``http://olympia.dev``
|
||||
you'll need to edit your ``/etc/hosts`` file on your native operating system.
|
||||
For example::
|
||||
|
||||
[ip-address] olympia.dev
|
||||
|
||||
Typically the ip address is localhost 127.0.0.1 if you're using docker-machine

|
||||
the Docker vm.
|
||||
|
||||
You can ensure your docker server is configured internally with this host by
|
||||
setting it in the environment and restarting the docker containers, like this::
|
||||
By default we configure `OLYMPIA_SITE_URL` to point to `http://olympia.dev`.
|
||||
|
||||
If you choose a different hostname you'll need to set that environment variable
|
||||
and restart the Docker containers::
|
||||
|
||||
docker-compose stop # only needed if running
|
||||
export OLYMPIA_SITE_URL=http://olympia.dev
|
||||
export OLYMPIA_SITE_URL=http://[YOUR_HOSTNAME}
|
||||
docker-compose up -d
|
||||
|
||||
.. note::
|
||||
The default docker configuration already configures `OLYMPIA_SITE_URL` to
|
||||
be set to `http://olympia.dev`

Here's a list of a few of the issues you might face when using Docker.
|

|

Can't access the web server?
|
||||
----------------------------

||||
Check you've created an hosts file entry pointing ``olympia.dev`` to the
|
||||
relevant ip address.
|
||||
Check you've created a hosts file entry pointing ``olympia.dev`` to the
|
||||
relevant IP address.
|
||||
|
||||
Also make sure you've copied ``docker-compose.override.yml.tmpl`` to
|
||||
``docker-compose.override.yml`` to get the default ports. If you haven't
|
||||
stop the containers with ``docker-compose stop`` copy the file and restart
|
||||
with ``docker-compose up -d``.
|
||||
|
||||
Another tip is to use ``docker-compose ps`` to check the status of the
|
||||
containers. If they are failing to start you should be able to tell here.
|
||||
If containers are failing to start use ``docker-compose ps`` to check their
|
||||
running status.
|
||||
|
||||
Another way to find out what's wrong is to run ``docker-compose logs``.
|
||||
|
||||
Getting "Programming error [table] doesn't exist"?
|
||||
--------------------------------------------------
|
||||
|
||||
Check you've run the ``make initialize_docker`` step.
|
||||
Make sure you've run the ``make initialize_docker`` step as detailed in
|
||||
the initial setup instructions.
|
||||
|
||||
|
||||
Port collisions (nginx container fails to start)
|
||||
------------------------------------------------
|
||||
|
||||
Since by default the docker-compose file exposes the port to the nginx
|
||||
server that sits in front of the web service on port 80 on your host
|
||||
you might find it fails to start if you're already running a service on
|
||||
port 80.
|
||||
|
||||
This problem will manifest itself by the services failing to start, you'll
|
||||
be able to see the error like so::
|
||||
If you're already running a service on port 80 or 8000 on your host machine,
|
||||
the ``nginx`` container will fail to start. This is because the
|
||||
``docker-compose.override.yml`` file tells ``nginx`` to listen on port 80
|
||||
and the web service to listen on port 8000 by default.
|
||||
|
||||
This problem will manifest itself by the services failing to start. Here's an
|
||||
example for the most common case of ``nginx`` not starting due to a collision on
|
||||
port 80::
|
||||
|
||||
ERROR: for nginx Cannot start service nginx:.....
|
||||
...Error starting userland proxy: Bind for 0.0.0.0:80: unexpected error (Failure EADDRINUSE)
|
||||
ERROR: Encountered errors while bringing up the project.
|
||||
|
||||
There's a couple of ways to fix it. Simple one is to find out what's running on
|
||||
port 80 and stop it::
|
||||
You can check what's running on that port by using (sudo is required if
|
||||
you're looking at port < 1024)::
|
||||
|
||||
sudo lsof -i :80
|
||||
|
||||
We now specify the ports nginx listens on in the ``docker-compose.override.yml``
|
||||
file that you copied from ``docker-compose.override.yml.tmpl`` when going through
|
||||
the initial setup. The second solution to a port collision is to change the
|
||||
default port that's bound on the host.
|
||||
We specify the ports ``nginx`` listens on in the ``docker-compose.override.yml``
|
||||
file. If you wish to override the ports you can do so by creating a new ``docker-compose``
|
||||
config and starting the containers using that config alongside the default config.
|
||||
|
||||
If you need to change the ports you can do so by changing the defaults in
|
||||
``docker-compose.override.yml``.
|
||||
|
||||
For example if you want to run nginx on your host and still
|
||||
access the development environment on port 80 you can change
|
||||
``docker-compose.override.yml`` to this::
|
||||
For example if you create a file called ``docker-compose-ports.yml``::
|
||||
|
||||
nginx:
|
||||
ports:
|
||||
- 8880:80
|
||||
|
||||
Now the container nginx is listening on 8880 on the host. You can now proxy
|
||||
to the container nginx from the host nginx with the following nginx config::
|
||||
Next you would stop and start the containers with the following::
|
||||
|
||||
docker-compose stop # only needed if running
|
||||
docker-compose -f docker-compose.yml -f docker-compose-ports.yml up -d
|
||||
|
||||
Now the container ``nginx`` is listening on 8880 on the host. You can now proxy
|
||||
to the container ``nginx`` from the host ``nginx`` with the following ``nginx`` config::

||||
