I get following error when try to docker compose build mysql for laradock:

=> ERROR [laradock_mysql internal] load metadata for docker.io/library/mysql:latest

The command i ran:

docker-compose up -d nginx mysql phpmyadmin redis workspace

My solution is platform in your docker compose file (technically not resolve running MySQL on ARM):

mysql:platform: linux/amd64

1. Need to add a nameserver in /etc/resolv.conf file by running this to modify:

add
Listen 8080
2. touch xx.conf file in /etc/httpd/conf.d
3. edit this file xx.conf

5. if failed, change to port 8080, then repeat 1

<VirtualHost *:8080>
ServerName xx.com
DocumentRoot /var/www/html/xx/public

<Directory /var/www/html/xx>
AllowOverride All
</Directory>
</VirtualHost>

1. yum install policycoreutils
2. Add Selinux rules for port 8080.

semanage port -a -t http_port_t -p tcp 8080
semanage port -m -t http_port_t -p tcp 8080

Check running process (eg grep artisan (for artisan only))
ps aux|grep artisan

Stop running process
- can get PID from above
kill 88888

stop all artisan process
pkill -f artisan

1. vi /etc/php.d/10-opcache.ini
2. enable all of these by uncomment them:

opcache.enable_cli=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1

4. service httpd restart or systemctl restart nginx
