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 && \
    # Delete PHP source archive cache
    docker-php-source prune
  
  # Switch back to default user
  USER www-data
  

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 packages 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 && \
    # Delete PHP source archive cache
    docker-php-source prune
  
  # Switch back to default user
  USER www-data

• Note: Some PECL extension packages are not available to install. Extensions such as 'json', 'hash' and etc.
