Bitnami offers CodeIgniter development image which you can use as an alternative for the built-in spark.
There are some compromises: as per this time of writing, there are some points of discrepancy in the documentations. We found little to no online answer to issue that we've faced. Plus, the image is close-sourced.
The purpose of this file is to document list configurations that have been working for us.
The bitnami-no-db.yml is the bare minimum configuration that you can run. The composed container will not have access to database. This is useful to try/test codeigniter with the starter template we've provided.
Place this configuration file on the source root of this project, and run:
docker compose -f bitnami-no-db.yml up -d
The compose will mount /source at the working directory of the container.
Now, try to open the development session at localhost:8000.
For debugging, you should also be able to find this line inside the docker logs:
codeigniter4 | codeigniter 03:41:23.82 INFO ==> An existing project was detected, skipping project creation
This confirms that the /source has been mounted correctly,
and that bitnami/codeigniter use the provided source code
instead of bootstrapping another new one.
The site should now be served at localhost:8000.
This configuration will make both db-main and db-test container accessible to the
code igniter development image.
Both of the databases can still be accessed from host (e.g. using MySQL Client).
First, change the content of docker-compose.yml on the root of the project with bitnami-with-db.yml.
Update your .env file to adjust the hostname and port for both main and the test database:
database.default.hostname = db-main
database.default.port = 3306
database.tests.hostname = db-test
database.tests.port = 3306
Spin up the compose file:
docker compose up -d
Confirms that your codeigniter4 container can connect with the MySQL container
by running the test command:
docker exec -w /app/starter-ci4/ codeigniter4 composer run-script test
The test should be succeeded without any error.
The site should now be served at localhost:8000.
Command can be executed inside the codeigniter4 container using docker exec
with /app/<PROJECT_NAME> as the working directory.
The PROJECT_NAME may vary according to what is being supplied as CODEIGNITER_PROJECT_NAME inside the compose file.
For example, to get the list of all installed PHP Modules:
docker exec -w /app/starter-ci4/ codeigniter4 php -v
