azure - azure自托管代理linux不能与 “--once”参数一起运行

Question

我喜欢每个管道只运行一次自托管的Linux容器
这意味着当管道完成时，我希望容器停止
我看到有一个名为“--once”的参数
请将此链接放在底部:
https://docs.microsoft.com/en-us/azure/devops/pipelines/agents/docker?view=azure-devops
但是当我运行一次后像这样启动docker时:

docker run --once --rm -it -e AZP_WORK=/home/working_dir -v /home/working_dir:/azp -e AZP_URL=https://dev.azure.com/xxxx -e AZP_TOKEN=nhxxxxxu76mlua -e AZP_AGENT_NAME=ios_dockeragent xxx.xxx.com:2000/azure_self_hosted_agent/agent:latest 

我越来越 :

unknown flag: --once
See 'docker run --help'.

如果我把它放在docker文件中
如

COPY ./start.sh .
RUN chmod +x start.sh

CMD ["./start.sh --once"]

我在尝试运行docker时收到错误消息:docker: Error response from daemon: OCI runtime create failed: container_linux.go:349: starting container process caused "exec: \"./start.sh --once\": stat ./start.sh --once: no such file or directory": unknow n
我在哪里需要在dockerized代理中设置此“--once”命令？

用于代理的run，而不是docker run。来自docs:

For agents configured to run interactively, you can choose to have the agent accept only one job. To run in this configuration:

./run.sh --once

Agents in this mode will accept only one job and then spin down gracefully (useful for running in Docker on a service like Azure Container Instances).

因此，您需要将其添加到配置docker镜像的bash脚本中:

FROM ubuntu:18.04

# To make it easier for build and release pipelines to run apt-get,
# configure apt to not require confirmation (assume the -y argument by default)
ENV DEBIAN_FRONTEND=noninteractive
RUN echo "APT::Get::Assume-Yes \"true\";" > /etc/apt/apt.conf.d/90assumeyes

RUN apt-get update \
&& apt-get install -y --no-install-recommends \
        ca-certificates \
        curl \
        jq \
        git \
        iputils-ping \
        libcurl4 \
        libicu60 \
        libunwind8 \
        netcat

WORKDIR /azp

COPY ./start.sh .
RUN chmod +x start.sh --once
