I am trying to move my existing multisite network to the Docker/Kubernetes setup for easy backup and management.
I have an environment setup at
MYSQL : 5.7.2
PHPMYADMIN: Latest
WordPress: 5.6 (the PHP version in this installation is 7.3 which I need to update)
I want to upgrade to PHP 8.0.0
I was suggested to use a docker file which I did,
–> https://github.com/docker-library/wordpress/blob/5bbbfa8909232af10ea3fea8b80302a6041a2d04/latest/php8.0/apache/Dockerfile
When running this with a correction in line 149 :
RUN ["chmod", "+x", "docker-entrypoint.sh"]
ENTRYPOINT ["./docker-entrypoint.sh"]
CMD ["apache2-foreground"]
I get the following error,
ERROR: for wordpress Cannot start service wordpress: OCI runtime create failed: container_linux.go:380: starting container process caused: exec: "docker-entrypoint.sh": executable file not found in $PATH: unknown
ERROR: Encountered errors while bringing up the project.
PS C:Usersdev> docker-compose up -d
dev_db_1 is up-to-date
Starting dev_wordpress_1 …

I need your help in getting my WordPress image running, I am unsure about what does this, (docker-entrypoint.sh)
contain, or where to place it.
Your help and guidance is well appreciated in advance.

You can find the script
docker-entrypoint.sh
at https://github.com/docker-library/wordpress/tree/5bbbfa8909232af10ea3fea8b80302a6041a2d04/latest/php8.0/apache, the same folder where you get the Dockerfile.docker-entrypoint.sh
is the script that is executed once the Docker image is loaded (so as the name says it’s the image entry-point).I’m able to build and load the WordPress image with PHP 8.0 and Apache with the following commands:
Now I’m able to connect to the site http://127.0.0.1:8000/
No need of any correction.
Note that you can use
docker
instead ofpodman
, if you prefer.Works also with this simple
docker-compose
file:sudo docker-compose up
.Actually you should not try to update php inside a docker container.
Instead find out how the container is built, then build one that contains the php version you desire. This will keep the image simple and small.
