ungültigen Header-Feld Wert „OCI-Laufzeitfehler während Docker Bild läuft

Question

ich unter Dockerfile für zookeeper Setup haben, und ich habe für das Docker Bild gebaut

FROM openjdk:8-jre-alpine

    bash \ 
    su-exec

RUN set -x \

    && wget -q "http://www.apache.org/dist/zookeeper/$DISTRO_NAME/$DISTRO_NAME.tar.gz" \

    && gpg --batch --verify "$DISTRO_NAME.tar.gz.asc" "$DISTRO_NAME.tar.gz" \ 
    && tar -xzf "$DISTRO_NAME.tar.gz" \ 
    && mv "$DISTRO_NAME/conf/"* "$ZOO_CONF_DIR" \ 
    && rm -r "$GNUPGHOME" "$DISTRO_NAME.tar.gz" "$DISTRO_NAME.tar.gz.asc" \ 
    && apk del .build-deps 

WORKDIR $DISTRO_NAME

EXPOSE $ZOO_PORT 2888 3888 

ENV PATH=$PATH:/$DISTRO_NAME/bin \ 
    ZOOCFGDIR=$ZOO_CONF_DIR 

COPY docker-entrypoint.sh/
ENTRYPOINT ["/docker-entrypoint.sh"] 
CMD ["zkServer.sh", "start-foreground"] 

Ich baue es wie folgt aus:

root@duo4:/home/david/zookeeper-docker# docker build -t david/zookeeper:3.4.9 . 

Wenn ich die zookeeper Instanz laufen, erhalte ich diese Fehlermeldung:

root@duo4:/home/david/zookeeper-docker# docker run --name zookeeper --restart always -d david/zookeeper:3.4.9 
24a282f2d04f1b638820a63a2037f618621d315d8c1cdb62aed609426bb19045 
docker: Error response from daemon: invalid header field value "oci runtime error: container_linux.go:247: starting container process caused \"exec: \\\"/docker-entrypoint.sh\\\": permission denied\"\n". 

Was ist hier falsch ich habe alle meine Dateien, die ich? nside zookeeper-docker Verzeichnis. Auch ich gab chmod +x persmission auf docker-entrypoint.sh in meinem aktuellen Verzeichnis.

Im Folgenden ist der Inhalt der docker-entrypoint.sh

#!/bin/bash 

set -e 

# Allow the container to be started with `--user` 
if [ "$1" = 'zkServer.sh' -a "$(id -u)" = '0' ]; then 
    chown -R "$ZOO_USER" "$ZOO_DATA_DIR" "$ZOO_DATA_LOG_DIR" 
    exec su-exec "$ZOO_USER" "$0" "$@" 
fi 

# Generate the config only if it doesn't exist 
if [ ! -f "$ZOO_CONF_DIR/zoo.cfg" ]; then 
    CONFIG="$ZOO_CONF_DIR/zoo.cfg" 

    echo "clientPort=$ZOO_PORT" >> "$CONFIG" 
    echo "dataDir=$ZOO_DATA_DIR" >> "$CONFIG" 
    echo "dataLogDir=$ZOO_DATA_LOG_DIR" >> "$CONFIG" 

    echo "tickTime=$ZOO_TICK_TIME" >> "$CONFIG" 
    echo "initLimit=$ZOO_INIT_LIMIT" >> "$CONFIG" 
    echo "syncLimit=$ZOO_SYNC_LIMIT" >> "$CONFIG" 

    for server in $ZOO_SERVERS; do 
     echo "$server" >> "$CONFIG" 
    done 
fi 

# Write myid only if it doesn't exist 
if [ ! -f "$ZOO_DATA_DIR/myid" ]; then 
    echo "${ZOO_MY_ID:-1}" > "$ZOO_DATA_DIR/myid" 
fi 

exec "$@" 

Im Folgenden wird die Ausgabe:

Answer 1

Ihre docker-entrypoint.sh nicht ausführbar ist, benötigen Sie einen RUN chmod 755 /docker-entrypoint.sh nach dem COPY Befehl hinzufügen in Ihrer Dockerfile und erstellen Sie das Image neu.
