【Devops】 - Azure Devops的代理池：封装一个自己的代理池镜像

生成代理也是一台机器，是可以给AzureDevops远程调用的机器，它的功能就是想手动对程序进行生成编译一样的封装的自动化操作，它的动作包括拉取代码，按照生成逻辑进行编译，封装镜像，推送镜像，部署的过程，但是如果编译频繁，那么一台生成代理可能是不够的，所以我们封装一个docker镜像，随时部署，或者部署到多个地方进行分摊。

新建一个start.sh,将下面的代码段存入其中，它的主要功能就是使用环境变量对代理池进行配置与启动，就是我们新建代理池的时候要执行的./config.sh配置与./run.sh启动代理池的操作。

#!/bin/bash
set -e

if [ -z "$AZP_URL" ]; then
  echo 1>&2 "error: missing AZP_URL environment variable"
  exit 1
fi

if [ -z "$AZP_TOKEN_FILE" ]; then
  if [ -z "$AZP_TOKEN" ]; then
    echo 1>&2 "error: missing AZP_TOKEN environment variable"
    exit 1
  fi

  AZP_TOKEN_FILE=/azp/.token
  echo -n $AZP_TOKEN > "$AZP_TOKEN_FILE"
fi

unset AZP_TOKEN

if [ -n "$AZP_WORK" ]; then
  mkdir -p "$AZP_WORK"
fi

export AGENT_ALLOW_RUNASROOT="1"

cleanup() {
  if [ -e config.sh ]; then
    print_header "Cleanup. Removing Azure Pipelines agent..."

    # If the agent has some running jobs, the configuration removal process will fail.
    # So, give it some time to finish the job.
    while true; do
      ./config.sh remove --unattended --auth PAT --token $(cat "$AZP_TOKEN_FILE") && break

      echo "Retrying in 30 seconds..."
      sleep 30
    done
  fi
}

print_header() {
  lightcyan='\033[1;36m'
  nocolor='\033[0m'
  echo -e "${lightcyan}$1${nocolor}"
}

# Let the agent ignore the token env variables
export VSO_AGENT_IGNORE=AZP_TOKEN,AZP_TOKEN_FILE

print_header "1. Determining matching Azure Pipelines agent..."

if [ -z "$AZP_AGENT_PACKAGE_LATEST_URL" -o "$AZP_AGENT_PACKAGE_LATEST_URL" == "null" ]; then
  echo 1>&2 "error: could not determine a matching Azure Pipelines agent"
  echo 1>&2 "check that account '$AZP_URL' is correct and the token is valid for that account"
  exit 1
fi

print_header "2. Downloading and extracting Azure Pipelines agent..."

curl -LsS $AZP_AGENT_PACKAGE_LATEST_URL | tar -xz & wait $!

bash ./bin/installdependencies.sh

source ./env.sh

print_header "3. Configuring Azure Pipelines agent..."

./config.sh --unattended \
  --agent "${AZP_AGENT_NAME:-$(hostname)}" \
  --url "$AZP_URL" \
  --auth PAT \
  --token $(cat "$AZP_TOKEN_FILE") \
  --pool "${AZP_POOL:-Default}" \
  --work "${AZP_WORK:-_work}" \
  --replace \
  --acceptTeeEula & wait $!

print_header "4. Running Azure Pipelines agent..."

trap 'cleanup; exit 0' EXIT
trap 'cleanup; exit 130' INT
trap 'cleanup; exit 143' TERM

chmod +x ./run.sh

# To be aware of TERM and INT signals call run.sh
# Running it with the --once flag at the end will shut down the agent after the build is executed
./run.sh "$@" & wait $!

随后我们在同目录下创建一个dockerfile文件，用来对环境进行镜像封装。

ENV TARGETARCH=linux-x64

WORKDIR /azp

COPY ./start.sh .
RUN chmod +x start.sh
ENTRYPOINT [ "./start.sh" ]

docker build -t azp-azent:debian.11.3 .
docker push azp-azent:debian.11.3


#docker build -t privatedocker.xxx.xxx/namespace/azp-azent:debian.11.3 .
#docker push privatedocker.xxx.xxx/namespace/azp-azent:debian.11.3

如此就打包完成了。
