I have one docker image that run successfully on one host (host 1) , but on host 2 and 3, Jersey classes are not getting loaded.
I am using Jersey for creating a rest api in java.
My dockerfile is
FROM tomcat:8.0.51-jre8-alpine
COPY ./reasoner-api/target/reasoner-api.war /usr/local/tomcat/webapps/reasoner-api.war
EXPOSE 8080CMD [“catalina.sh”,“run”]
I run the docker as:
docker run -d -p 8080:8080 -i -t semantic_web:latest
In host 1:
host 1: OC:Windows 10 pro OC Build 18363.900 64-bit
Docker version 19.03.8, build afacb8b
The jersey initiates successfully the classes of the rest api:
