I am unable to upgrade my PHP version in my docker wordpress installation

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:\Users\dev> docker-compose up -d dev_db_1 is up-to-date Starting dev_wordpress_1 ... Starting dev_wordpress_1 ... error

ERROR: for dev_wordpress_1 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: 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.

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.

Regards, Aaditya

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.

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:

git clone https://github.com/docker-library/wordpress.git
cd wordpress/latest/php8.0/apache
podman build -t wordpress_php8 .
podman run --rm -it -p 8000:80 localhost/wordpress_php8:latest

Now I'm able to connect to the site http://127.0.0.1:8000/

enter image description here

No need of any correction.

Note that you can use docker instead of podman, if you prefer.

Works also with this simple docker-compose file:

version: "3.9"
services:
  wordpress:
    build:
      context: "./"
      dockerfile: Dockerfile
    ports:
      - "8000:80"

sudo docker-compose up.
