在 bash 中完成代码构建后如何停止执行？

如何解决在 bash 中完成代码构建后如何停止执行？

我正在创建一个脚本，用于在 AWS Codebuild 中启动构建。除了运行它之外，我希望当构建完成（到达 COMPLETED 阶段）并读取字符串“COMPLETED”时，它会停止。

这是脚本：

#!/bin/bash
# Deploy API Gateway Authorizer

BUILD_PROJECT=$1
ENVIRONMENT=$2

if [ -z "$BUILD_PROJECT" ]
then
    echo "BUILD_PROJECT is empty,exiting...."
    exit 1
fi

if [ -z "$ENVIRONMENT" ]
then
    echo "ENVIRONMENT is empty,exiting...."
    exit 1
fi

function getStatus {
    id=$(aws codebuild list-builds-for-project --project-name "${BUILD_PROJECT}-${ENVIRONMENT}" | jq -r '.ids[0]')
    aws codebuild batch-get-builds --ids "$id" | jq '.builds[].phases[] | select (.phaseType=="COMPLETED") | .phaseType'
}

echo "----------------------------------------------------"
echo "deploying: ${BUILD_PROJECT}-${ENVIRONMENT}"
echo "----------------------------------------------------"
aws codebuild start-build --project-name "${BUILD_PROJECT}-${ENVIRONMENT}"

while [ getStatus != "COMPLETED" ]
do
    echo "deploying..."
    sleep 5
    getStatus
done 

我已经用 getStatus 函数尝试了这个，然后在一个 while 循环中直到函数的结果 != "COMPLETED" 但即使它在控制台输出中显示 COMPLETED，它总是继续执行.

这是我运行脚本时的控制台输出，例如：

----------------------------------------------------
deploying: api-gateway-authorizer-us2-stage
----------------------------------------------------
deploying...
deploying...
deploying...
deploying...
deploying...
deploying...
deploying...
deploying...
deploying...
deploying...
deploying...
deploying...
deploying...
deploying...
"COMPLETED"
deploying...
"COMPLETED"
deploying...
"COMPLETED"
deploying...
"COMPLETED"
deploying...

解决方法

您的 COMPLETE 实际上是 "COMPLETE"，因为您没有在 -r 中使用 jq 标志。此外，您必须将 getStatus 包装为 $(getStatus) 并在循环中使用 [[：

#!/bin/bash
# Deploy API Gateway Authorizer

BUILD_PROJECT=$1
ENVIRONMENT=$2

if [ -z "$BUILD_PROJECT" ]
then
    echo "BUILD_PROJECT is empty,exiting...."
    exit 1
fi

if [ -z "$ENVIRONMENT" ]
then
    echo "ENVIRONMENT is empty,exiting...."
    exit 1
fi

function getStatus {
    id=$(aws codebuild list-builds-for-project --project-name "${BUILD_PROJECT}-${ENVIRONMENT}" | jq -r '.ids[0]')
    aws codebuild batch-get-builds --ids "$id" | jq -r '.builds[].phases[] | select (.phaseType=="COMPLETED") | .phaseType'
}

echo "----------------------------------------------------"
echo "Deploying: ${BUILD_PROJECT}-${ENVIRONMENT}"
echo "----------------------------------------------------"
aws codebuild start-build --project-name "${BUILD_PROJECT}-${ENVIRONMENT}"

while [[ $(getStatus) != "COMPLETED" ]]
do
    echo "Deploying..."
    sleep 5
    getStatus
done
