RE: Tomcat in distroless image
CONFIDENTIAL & RESTRICTED
Just my 2 cents...
Tomcat is based on Java.
AFAIK java itself needs a wide range of 'OS services'. Is there some distributionless java image around?

Hi,
Sadly currently Tomcat startup relies on shell script to bootstrap JVM process.
In the light of distroless images (e.g. https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fblog.chainguard.dev%2Fintroducing-apko-bringing-distroless-nirvana-to-alpine-linux%2F&data=05%7C01%7C%7Ca362b5381ee24ff6446608da5ac15ec7%7Cb3f4f7c272ce4192aba4d6c7719b5766%7C0%7C0%7C637922083809078548%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=Rf8VAfyRfwsCXQaiVsdgefafatLAJYuqBE%2FR6sYoxOk%3D&reserved=0)
what are you thoughts on packaging tomcat in distroless base OCI images that doesn't even contain any shell anymore?
Would it be possible to provide an alternative start mechanism which directly starts JVM process which setup/prepare env like the current catalina.sh shell script does?
What are your thoughts on above topic?
Mfg
Thomas
