A Docker network with containers as a base layer for development.

This setup uses Traefik as a reverse proxy to serve as an entrypoint for your applications during development

• Traefik

Requirements

• Docker
• Docker-compose
• PHP7.4+
• Composer

Starting Koala

If you start, it will by default start:

• Traefik
• Mariadb
• MySQL 8
• Postgres
• Mailcatcher

These are the base services created in the docker network "koala".

note: You might be asked for your system user password the first time. This is the case if you need administrator privileges to create the root certificate authority for koala.

SSL

Certificates are generated for the services where you apply the configuration for it.

The TLD (top level domain) used is docker. A root certificate is generated to sign all other application certificates. So you can trust the root certificate and all other signed certificates will be valid by parent certificate.

You can find the root certificate here:

• ~/.koala-persistent/ssl/certs/_koala-ca-root-certificate.crt

Simply trust it as CA in the browser or your machine globally.

Traefik

What traefik allows you to do is make services/containers accessible via http(s), tcp or udp routes. So say for example you have a nginx webservice container in your project. Simply add it to the koala network in docker and add Traefik labels to add the correct routning.

You can access the Traefik dashboard on localhost:8000

More documentation and automation on how to apply and use this in projects will follow...

Maria db

Mariadb is started on port 3308 and accessible on host on

• localhost:3308

Or in de Koala network on

• mariadb103.services.docker:3308

Root username & password are:

• root / password

PostgreSQL

Postgres is started on port 5434 and accessible on host on

• locahost:5434

Or in the Koala network on

• postgres11.services.docker:5434

Root username & password are:

• root / password

Mailcatcher

For testing mails there is a container running. This is accessible in the browser on mail.docker

So be sure to point mail.docker to 127.0.0.1 and/or ::1 in your hosts file.

127.0.01 mail.docker

::1 mail.docker

A certificate is generated on creation of the container. See The SSL section for more on that

Compose services

Aside from the basic containers that are created you can choose for the option "Compose service".

This shows the extra services you can start. For now this is just Elasticsearch 7.17 & Kibana.

When you start this you'll have an elasticsearch node available on:

• localhost:9202

Or in the koala network as:

• elasticsearch7.services.docker:9202

Kibana will be started (this can take a few seconds), you can access it on:

• kibana.elasticsearch7.docker

Also be sure to point "kibana.elasticsearch7.docker" to 127.0.0.1 and/or ::1.

/etc/hosts

127.0.07    kibana.elasticsearch7.docker
::1         kibana.elasticsearch7.docker

Create a new php/nginx project

If you want to create a project with a php & nginx container run:

koala create:project

• Enter a domain name
• Follow steps given in the out
