我有一个运行Kong-api的Dockerfile，可以在openshift上进行部署。它可以建立，但是当我检查吊舱时，我得到了Back-off restarting failed container。这是我的dockerfile

FROM ubuntu:18.04
RUN apt-get update && apt-get install -y apt-transport-https curl lsb-core
RUN echo "deb https://kong.bintray.com/kong-deb `lsb_release -sc` main" | tee -a /etc/apt/sources.list
RUN curl -o bintray.key https://bintray.com/user/downloadSubjectPublicKey?username=bintray
RUN apt-key add bintray.key
RUN apt-get update && apt-get install -y kong

COPY kong.conf /etc/kong/
RUN kong migrations bootstrap [-c /etc/kong/kong.conf]

EXPOSE 8000 8443 8001 8444
ENTRYPOINT ["kong","start","[-c /etc/kong/kong.conf]"]

我哪里错了？请帮我。预先感谢
