Question

我有一个泊坞窗文件，该文件应该在ENTRYPOINT中运行shell脚本，但似乎代码未运行。

我尝试使用＃！/ bin / sh，＃！/ bin / bash或完全删除的shebang进行游戏，如此处所述：Stackoverflow。我还使用了ENTRYPOINT或CMD。此外，我使用dos2unix转换了unix中的每个文件，但每次都得到相同的结果。

该图像在一个由Dockerfile构建的无业游民的文件中调用

    config.vm.provision "docker" do |d|
    d.build_image "/vagrant",
        args: "-t keycloak-image"
    d.run "keycloak",
        image: "keycloak-image:latest",
        args: "-p 8080:8080 -e KEYCLOAK_USER=admin -e KEYCLOAK_PASSWORD=admin -e DB_VENDOR=H2"

  end

这是当前的Dockerfile

FROM jboss/keycloak:latest

USER root

# copy from /setup into /opt/jboss/setup
COPY /setup /opt/jboss/setup

#use opt/jboss/setup as working directory 
WORKDIR /opt/jboss/setup

#take he run and load script and convert it to a unix script by deleting /r with the tr pipe and -d (delete) 
RUN cat /opt/jboss/setup/run.sh | tr -d '\r' > /opt/jboss/setup/run.sh
RUN cat /opt/jboss/setup/load.sh | tr -d '\r' > /opt/jboss/setup/load.sh

ENTRYPOINT ["sh","./run.sh"]

和当前的shell脚本

#!/bin/sh

function is_keycloak_running {
    local http_code=$(curl -s -o /dev/null -w "%{http_code}" http://localhost:${KEYCLOAK_PORT}/auth/admin/realms)
    if [[ $http_code -eq 401 ]]; then
        return 0
    else
        return 1
    fi
}

function configure_keycloak {
    until is_keycloak_running; do
        echo Keycloak still not running, waiting 5 seconds
        sleep 5
    done
    echo Keycloak is running, proceeding with configuration
    echo Now run load script inside run script
    ./load.sh
}

if [ ! -f ${JBOSS_HOME}/standalone/data/docker-container-configuration-done ]; then
    touch ${JBOSS_HOME}/standalone/data/docker-container-configuration-done
    configure_keycloak &
fi

# this is not in a volume, at least not by default, so we need to replace the port every time the server runs
sed -i -e 's/<socket-binding name="http".*/<socket-binding name="http" port="'$KEYCLOAK_PORT'"\/>/' ${JBOSS_HOME}/standalone/configuration/standalone.xml

${JBOSS_HOME}/bin/add-user-keycloak.sh --user $KEYCLOAK_USER --password $KEYCLOAK_PASSWORD

${JBOSS_HOME}/bin/standalone.sh -b 0.0.0.0

输出

如您所见，输出中没有回声。此外，该程序未在localhost：8080上运行，但是如果我删除ENTRYPOINT，则该程序可用。因此，该脚本不起作用，有人知道吗？

感谢您的帮助
