對于 K8 的專家來說，這聽起來像是一個非常愚蠢的問題。但是我已經為此苦苦掙扎了一段時間，因此是下面的問題。我正在嘗試通過 Minikube 和 docker 在本地部署一個簡單的 Kubernetes 應用程序來測試 sidecar 容器模式。讓我們從邊車容器元素開始：文件FROM python:3.6-alpineRUN pip install boto3==1.14.20RUN pip install --upgrade awscli s3cmd   ENV APP_HOME_DIR=/home/sidecarRUN mkdir $APP_HOME_DIRADD run.sh $APP_HOME_DIRADD s3_sync.py $APP_HOME_DIRRUN chmod +x $APP_HOME_DIR/s3_sync.pyRUN chmod +x $APP_HOME_DIR/run.shENV BUCKET_NAME=ENV PROJECT_NAME=ENV FEATURE_BRANCH=ENV LOCAL_DIR=WORKDIR $APP_HOME_DIRENTRYPOINT ["./run.sh"]run.sh#!/bin/shwhile truedo    echo "Triggering an S3-SYNC"    python /home/sidecar/s3_sync.py -b $BUCKET_NAME -p $PROJECT_NAME -f $FEATURE_BRANCH -l $LOCAL_DIR    sleep 10done以及 python 文件s3_sync.py的簡化版本：import loggingimport argparselogging.basicConfig(    level=logging.INFO,    format="%(asctime)s [%(levelname)s] %(message)s",    handlers=[logging.FileHandler("debug.log"), logging.StreamHandler()],)logger = logging.getLogger(__name__)MASTER = "master"def main():    bucket_name = args.bucket_name    project_name = args.project_name    branch = args.feature_branch    local_dir = args.local_dir    sync_type = "production" if branch == MASTER else "review"    logger.info(f"S3-SYNC starting for {sync_type} environment")if __name__ == "__main__":    parser = argparse.ArgumentParser()    parser.add_argument("-b", "--bucket_name", help="s3 bucket name", required=True)    parser.add_argument("-p", "--project_name", help="project name to sync", default="")    parser.add_argument("-f", "--feature_branch", help="git feature branch name", default="master")    parser.add_argument("-l", "--local_dir", help="local dir where to sync the s3 objects", required=True)    args = parser.parse_args()    main()如果我構建上面的內容并運行它：docker build -t sidecar_python .docker run -e BUCKET_NAME=MYBUCKET -e PROJECT_NAME=MYPROJECT -e FEATURE_BRANCH=MYBRANCH -e LOCAL_DIR=/home sidecar_python事情進展順利。
