XDEBUG

Use idekey PHPTEST

PHPStorm

Debug config for IDE PHPStorm:

1. Add server:
   • Settings -> Languages -> PHP -> Servers
   • Name: localhost
   • Host: localhost
   • Port: 80
   • Debugger: Xdebug
   • Use path mapping: checked
   • Absolute path on the server: /var/www/html

2. Add PHP remote debug
   • Run / Debug Configurations -> PHP remote debug
   • Use server created in step #1 and set idekey PHPTEST

3. Enable Start listening for PHP Debug Connections

VSCode

Debug config for IDE VSCode here

Cron debugging

Follow previous steps, set a breakpoint and then run:

docker-compose exec php-fpm php admin/cli/cron.php

There is a scrip for Specific cron tasks. For example:

docker-compose exec php-fpm php admin/tool/task/cli/schedule_task.php --execute='\core\task\cache_cleanup_task'
# Listing tasks
# docker-compose exec php-fpm php admin/tool/task/cli/schedule_task.php --list

Pgadmin4

Config pgadmin4

1. Go to http://localhost:5050
2. In File -> Preferences -> Binary paths set /usr/bin
3. Add new server:
   • Tab General
     • Name: Any name you want
   • Tab Connection
     • Host name/address: postgres
     • Host Username: user
     • Host Password: password
   • Save

Backup and restore database

When needed, backup and restore of the database could be done in the following way.

# Set env vars
POSTGRES_USER=user
POSTGRES_DB=moodle
DB_DUMP_NAME=dump-init.$(date +"%Y%m%d%H%M%S").dump

# Backup
# -Fc  Output a custom-format archive suitable for input into pg_restore
docker-compose exec postgres pg_dump -U ${POSTGRES_USER} ${POSTGRES_DB} -Fc -f /opt/db_dumps/${DB_DUMP_NAME}

# Restore
# -c  Clean (drop) database objects before recreating them.
# -C  Create the database before restoring into it
docker-compose exec postgres pg_restore -U ${POSTGRES_USER} -d postgres -c -C -O --role ${POSTGRES_USER} /opt/db_dumps/${DB_DUMP_NAME}

A database can be automatically restored when postgres service starts. By placing a dump file inside 'db_dumps' folder and naming it "dump-init.dump", postgres container will try to restore that file as an initial database if data directory is empty.

IMPORTANT: Depending of size, database initial availability could be delayed

Respaldar y restaurar la base de datos

Es posible respaldar y restaurar la base de datos de la siguiente manera.

# Establecer vars de entorno
POSTGRES_USER=user
POSTGRES_DB=moodle
DB_DUMP_NAME=dump-init.$(date +"%Y%m%d%H%M%S").dump

# Respaldar
# -Fc  Formato personalizado para pg_restore
docker-compose exec postgres pg_dump -U ${POSTGRES_USER} ${POSTGRES_DB} -Fc -f /opt/db_dumps/${DB_DUMP_NAME}

# Restaurar
# -c  Limpia los objetos de la base de datos antes de recrearlos
# -C  Crea la base de datos antes de restaurarla
docker-compose exec postgres pg_restore -U ${POSTGRES_USER} -d postgres -c -C -O --role ${POSTGRES_USER} /opt/db_dumps/${DB_DUMP_NAME}

Se puede restaurar una base de datos, usando pg_dump (formato personalizado de Posgres), a la caperta 'db_dumps' y nombrando el archivo como dump-init.dump

IMPORTANTE: Dependiendo del tamaño, la ejecución de este sql podría demorar la disponibilidad inicial de la base de datos.

any idea??

Performance issues

I'm starting to have a somewhat bad UX because of long response delays (~4 to 15 seconds depending on the task), even if i'm the only one using it (and the server where it is running is quite powerful)
I was wondering if you have had a similar problem, and if so, how did you tackle it?

Error on git clone

Hello,
it happens on exec the second command, i had only changed the moodle branch

git clone --branch MOODLE_39_STABLE --depth 1 git://github.com/moodle/moodle html

I get this error:

    Clone in 'html' in corso...
    fatal: impossibile collegarsi a github.com:
    github.com[0: 140.82.121.3]: errno=Connessione scaduta

I do this workaround , i hope is right, to get the goal

 git clone git://git.moodle.org/moodle.git html
 cd html
 git branch --track MOODLE_39_STABLE origin/MOODLE_39_STABLE
 git checkout MOODLE_39_STABLE

Thank'you,
Bye

Image doesn't work with a reverse proxy.

Hi Team

I need work with Moodle under a reverse proxy, but the Moodle containers doesn't work with a reverse proxy.

This is my Docker compose file for the reverse proxy:

version: '2'
services:
  nginx-proxy:
    image: jwilder/nginx-proxy
    container_name: nginx-proxy
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro
      - /var/www/vhost.d:/etc/nginx/vhost.d
      - /var/www/certs:/etc/nginx/certs:ro
      - /usr/share/nginx/html
    labels:
      - com.example.nginx_proxy=true

volumes:
  nginx-proxy:


networks:
  default:
    external:
      name: nginx-proxy

I only add the external network into the moodle docker-compose file.
when set up the moodle's containers I never see the moodle webpage.

Best regards.

Xdebug could not open the remote debug file

Hi Job,

I'm getting this error next:

Got error 'PHP message: Xdebug could not open the remote debug file '/var/log/xdebug.log'.\nPHP message: Xdebug could not open the remote debug file '/var/log/xdebug.log'.\n', referer: http://localhost/my/

I'm assuming this means a folder + file on my local machine so I've set the permissions to 766 / 777 respectively and there doesn't seem to make a difference.

Recommendations?

Moodle 39 Database Error

Hi, i'm giving a shot to upgrading the project to MOODLE_39_STABLE, to enhance plugin compatibility as much as possible.
Apparently everything runs OK, until i try to restore my previous database dump:

This is my updated install script:

#!/bin/bash
docker-compose down --volumes
docker system prune -af
docker-compose up -d
POSTGRES_USER=admin
POSTGRES_DB=moodle
DB_DUMP_NAME=dump-init.20201120185818.dump
docker-compose exec postgres pg_restore -U ${POSTGRES_USER} -d postgres -c -C -O --role ${POSTGRES_USER} /opt/db_dumps/${DB_DUMP_NAME}⏎  

Docs say that Moodle should be upgradeable from 35 to 39 as long as you install a clean project, copy your plugins and configs, and let moodle auto-update its database. However and if i understood correcly, here we have both user data and moodle database merged into postgress.
Is it upgradeable, or i must start with a fresh install?? If the last is the case, lets say i install plugins manually in a fresh-updated install, how do i restore user data?

Unmet dependencies

Hi Job,

Followed your quick start instructions, and I'm seeing this error and was curious if I was doing something wrong?

• Paul

ERROR: Service 'php-fpm' failed to build: The command '/bin/sh -c apt-get install -y graphviz clamav clamav-daemon zip unzip aspell-es' returned a non-zero code: 100

Reason: DNS lookup failure for: php-fpm

Hola,
cuando intento conectarme con Moodle, me aparece este mensaje:

Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request

Reason: DNS lookup failure for: php-fpm

Apache/2.4.25 (Debian) Server at 127.0.0.1 Port 80

Al parecer no me levanta en Docker docker-compose-moodle_php-fpm_1metics/php-fpm:7

Se inicia y se apaga
En los log solo me indica: : invalid option

Tampoco levanta este docker: docker-compose-moodle_app_1tianon/true
aunque me da Exit Code 0

Gracias.
