The only absolute requirement is Java 8 or newer—either the Oracle JRE or OpenJDK will work. Optional components, like particular resolvers, processors, or caches, may have additional requirements.
The distribution archive bundles a sample configuration file, named cantaloupe.properties.sample. Do not edit this file—create a copy and edit that. The documentation refers to this file as cantaloupe.properties, but it can be named anything.
Next, open the file in a text editor and set
FilesystemResolver.BasicLookupStrategy.path_prefix to a folder path containing some images.
Cantaloupe is distributed as a custom .war file that can be run standalone (using a built-in web server) or deployed to a Servlet container like Tomcat. If you have a choice, standalone mode is generally recommended, as it's less prone to conflicts with other applications.
From the command prompt (macOS/Linux):
java -Dcantaloupe.config=/path/to/cantaloupe.properties -Xmx2g -jar Cantaloupe-3.4.x.war
From the command prompt (Windows):
java -Dcantaloupe.config=C:\path\to\cantaloupe.properties -Xmx2g -jar Cantaloupe-3.4.x.war
Assuming you have an image named image.tif, try accessing:
Copy the Cantaloupe-3.4.x.war file to your container's web application folder. (In Tomcat, this is /webapps inside the main Tomcat folder.)
-Dcantaloupe.config VM argument to your container, in the same format as in the standalone section. In Tomcat 8, this can be done by setting
CATALINA_OPTS, located in bin/setenv.sh (Unix) or bin/setenv.bat (Windows) inside the main Tomcat folder:
export CATALINA_OPTS="$CATALINA_OPTS -Dcantaloupe.config=/path/to/cantaloupe.properties"
set JAVA_OPTS=%JAVA_OPTS% -Dcantaloupe.config="C:\path\to\cantaloupe.properties"
Then, restart your container.
Assuming you have an image named image.tif, and a container listening on port 8080, try accessing:
The download archive doesn't include any Docker support files, but see these repositories for examples:
Before deploying to production, see Deployment for some important notes.
