Installing ImageMagick and Gifsicle Manually

2025.Q2.9+

ImageMagick and Gifsicle are removed from all Liferay Docker images starting with Liferay DXP 2025.Q2.9 and on the following quarterly releases. Patch releases for earlier quarterlies keep these tools, even if released after 2025.Q2.9.

Warning

Customers who install these tools are responsible for maintaining them and addressing any security issues.

1. Run the container as the root user:

   docker exec -u root -it [container_name_or_id] bash
   

2. Install the tool you need (imagemagick or gifsicle):

   apt-get update && apt-get install -y [tool_name]
   

After installation, ensure the container’s PATH environment variable includes the binary for the installed tool.
