Base Docker

About

Soon to be named something else?

A local dev environment for working on one or more Empathy apps. (See https://github.com/mikejw/empathy.)

For macOS/Linux workstations you must have Docker and Ansible installed on your local machine, however if you are on Windows, read the Windows instructions before reading the rest of this README, beginning at the "Usage" section.

Getting starting

Decide your local hostname:

Decide which local hostname you will be using for development.

The recommended custom hostname is www.dev.org.

You might decide to use an IP address instead (useful for testing from another device on your network), localhost, or something else entirely.

If you decide to use something other than www.dev.org, even if it is an IP address or is another custom hostname, make a note of it now.

Hosts file entry for www.dev.org or custom hostname:

Whether you are going with the default hostname www.dev.org or something custom, create a /etc/hosts file entry for it now if it is not a system default hostname. (IP address or localhost.) www.dev.org is being used in the following example:

127.0.0.1	localhost www.dev.org

Virtualenv in ./python:

Initialise virtualenv within the root directory of base-docker on your machine. (E.g. for macOS):

brew install virtualenv
virtualenv ./python

Install pip package packaging:

This package is a pre-requisite before pip packages can be installed through Ansible.

Install it manually now:

cd ./python/bin
./pip3 install packaging

Install Anisble galaxy roles/collections:

From the root base-docker directory, run the script as follows:

./ansible-install.sh

Usage

Initialise config on new machine:

cd dev/ansible
ansible-playbook ../init.yml

This creates settings file for base-docker in ~/.config.

If you are using any hostname other than the default (www.dev.org), specify it with the h argument. E.g:

cd dev/ansible
ansible-playbook ../init.yml -e "h=10.0.0.22"

Initialise global developer flag:

Running the init.yml playbook, by default will disable this global flag. It can be enabled with:

cd dev/ansible
ansible-playbook ../init.yml -e "dev=true"

When enabled, this currently ensures all composer dependencies are cloned (via git) during quickstart templating installs.

Switch project:

cd dev/ansible
ansible-playbook ../main.yml -e "op=switch cb=a.ce"

In the above example the project found in ~/code/a.ce will be set as active.

Boot current project:

cd dev/ansible
ansible-playbook ../main.yml -e "op=boot"

Quick-start commands:

Boostrap Empathy projects giving target extension template name. Template default is "vanilla" for base empathy app with no extensions, (when no argument is provided).

Others available are "elib-base", "elib-acl", "elib-blog" and "elib-cms".

NB: elib-cms dummy content (database dump data, image upload, footer background image) generated with ChatGPT!

The playbook will fail if codebase path already exists.

cd dev/ansible
ansible-playbook ../main.yml -e "op=qs cb=myproject tpl=elib-base"

Caveats

The default app container has apcu cache enabled for reading config.yml files and dependency injection services.php definition files.

Restart the app container after making changes to these files.

docker stop app
docker start app

Ansible my have trouble connecting to Docker Desktop on macOS when running docker tasks. If this happens run this command:

sudo ln -s "$HOME/.docker/run/docker.sock" /var/run/docker.sock
