gitbucket/gitbucket

I tried this Dockerfile

FROM adoptopenjdk/openjdk8-openj9

LABEL maintainer="Naoki Takezoe <takezoe [at] gmail.com>"

ADD https://github.com/gitbucket/gitbucket/releases/download/4.35.3/gitbucket.war /opt/gitbucket.war

RUN ln -s /gitbucket /root/.gitbucket

VOLUME /gitbucket

# Port for web page and Port for SSH access to git repository (Optional)
EXPOSE 8080 29418

CMD ["sh", "-c", "java -jar /opt/gitbucket.war"]

The output has similar warnings, however I can sign-in without any problem.
