Limitations =========== Unfortunately the AWS environment imposes several hard limits that are impossible to bypass: * The Docker container must fit within the current `AWS Lambda limits `_: * **Compressed + uncompressed** Docker image under **512 MB** (udocker needs to download the image before uncompressing it). * Maximum **execution time of 900 seconds** (15 minutes). * Installation of packages in the user-defined script (i.e. using `yum`, `apt-get`, etc.) is currently not possible.
