PHPMyAdmin on Docker with Laravel Sail POST Content-Length exceeds the limit - laravel

Question

I have a Laravel environment running on Docker via Sail on Mac OS X Big Sur. I added a phpmyadmin to my docker-compose.yml file and it's all working, but when I try to import my data to the database, I get:
Warning: POST Content-Length of 68109047 bytes exceeds the limit of 2097152 bytes in Unknown on line 0
I published the docker config files to my Laravel project and restarted docker. Here's my docker-composer.yml:
version: '3'
services:
laravel.test:
build:
context: ./docker/8.1
dockerfile: Dockerfile
args:
WWWGROUP: '${WWWGROUP}'
image: sail-8.1/app
extra_hosts:
- 'host.docker.internal:host-gateway'
ports:
- '${APP_PORT:-80}:80'
environment:
WWWUSER: '${WWWUSER}'
LARAVEL_SAIL: 1
XDEBUG_MODE: '${SAIL_XDEBUG_MODE:-off}'
XDEBUG_CONFIG: '${SAIL_XDEBUG_CONFIG:-client_host=host.docker.internal}'
volumes:
- '.:/var/www/html'
networks:
- sail
depends_on:
- mysql
mysql:
image: 'mysql/mysql-server:8.0'
ports:
- '${FORWARD_DB_PORT:-3306}:3306'
environment:
MYSQL_ROOT_PASSWORD: '${DB_PASSWORD}'
MYSQL_ROOT_HOST: "%"
MYSQL_DATABASE: '${DB_DATABASE}'
MYSQL_USER: '${DB_USERNAME}'
MYSQL_PASSWORD: '${DB_PASSWORD}'
MYSQL_ALLOW_EMPTY_PASSWORD: 1
volumes:
- 'sail-mysql:/var/lib/mysql'
networks:
- sail
healthcheck:
test: ["CMD", "mysqladmin", "ping", "-p${DB_PASSWORD}"]
retries: 3
timeout: 5s
myadmin:
image: 'phpmyadmin:latest'
ports:
- 8080:80
environment:
MYSQL_ROOT_PASSWORD: '${DB_PASSWORD}'
links:
- "mysql:db"
depends_on:
- mysql
networks:
- sail
networks:
sail:
driver: bridge
volumes:
sail-mysql:
driver: local
and in docker/8.1/php.ini
post_max_size = 100M
upload_max_filesize = 100M
variables_order = EGPCS
But still no luck. I also tried running this command and then at the prompt:
sail php -a
phpinfo();
Which revealed this:
Configuration File (php.ini) Path => /etc/php/8.1/cli
Loaded Configuration File => /etc/php/8.1/cli/php.ini
But there is no php folder in my /etc folder. I also noticed this in my docker config at docker/8.1/Dockerfile
COPY supervisord.conf /etc/supervisor/conf.d/supervisord.conf
COPY php.ini /etc/php/8.1/cli/conf.d/99-sail.ini
RUN chmod +x /usr/local/bin/start-container
But again, there is no /etc/php folder

Answer 1

According to https://hub.docker.com/_/phpmyadmin you need to specify in your docker-compose.yml file the environment variable UPLOAD_LIMIT to your desired limit. Eg.
myadmin:
image: 'phpmyadmin:latest'
ports:
- 8080:80
environment:
MYSQL_ROOT_PASSWORD: '${DB_PASSWORD}'
UPLOAD_LIMIT: 100000000
links:
- "mysql:db"
depends_on:
- mysql
networks:
- sail
so as to have an upload limit of 100.000.000 bytes.

Answer 2

This answer is not correct.
UPLOAD_LIMIT: 100000
specifies an limit of 100000 Bytes! So that is 97,66kB.
