⁠Samples

• Sample Dockerfiles: ./samples/⁠

⁠Advanced Usage

⁠Installing Extensions

To instal PHP extensions⁠ use docker-php-ext-install command. (This will enable the extension as well.)

• Available extensions to install

  • php-src/tree/master/ext⁠ | PHP @ GitHub

• Dockerfile sample to install gettext extension.

  FROM keinos/php8-jit:latest
  
  # You need a root access to install
  USER root
  
  RUN \
      # Install dependencies for gettext
      apk --no-cache add gettext-dev && \
      # Install gettext extension
      docker-php-ext-install gettext
  
  # Switch back to default user
  USER www-data
  
  

  Copy

⁠Installing PECL Packages

The PECL⁠ command is included. (Since build-20200825⁠, Issue #13⁠)

But as an alternative, you can use docker-php-ext-pecl install to install PECL package from source.

• Sample of installing YAML Functions⁠ of PECL from source.

  FROM keinos/php8-jit:latest
  
  # You need a root access to compile and install packages
  USER root
  
  RUN \
      # Install dependencies for YAML
      apk --no-cache add yaml-dev && \
      # Install PECL from source
      docker-php-ext-pecl install yaml
  
  # Switch back to default user
  USER www-data
  

  Copy

• Note: Some PECL extension packages are not available to install. Mostly the pre-built extensions such as 'json', 'hash' and etc.
