AWS ECS：任务被映射到错误的目标组
AWS ECS: Task Being Mapped to Wrong Target Group
我有一个包含 2 个模块的 Spring 项目：Pets 和 Owners，每个模块都是从单个 MySQL 数据库获取数据的微服务。当我将两者推入一个包含 2 个任务的 Docker 容器时——每个微服务 1 个——它们都启动并 运行，并且任务映射到不同的主机端口（32768 和 32769） .但是，当我转到 http://{elb-dns}/pet 时，我得到了 404，但是当我转到 http://{elb-dns}/owner 时，它 returns 预期的数据。我了解到宠物任务被映射到错误的目标组，但我不知道为什么。
创建 ECS 集群后，这是以下 AWS CLI "describe" 命令输出的内容：

我已经确认，当单独部署时，每个微服务都是独立工作的。我使用的是 Application Load Balancer，每个微服务都有自己的目标组。我不确定还有什么可以尝试或检查的。有没有人遇到过类似的问题？我还应该在哪里寻找线索？

同一个调用在 pet 任务中产生 no 日志，表明它没有被路由到容器中的正确任务。所以我仍然卡在这个问题上。
更新 2
ELB 日志显示，对于 /pet 和 /owner，所有调用都被路由到同一个目标组。但是，/pet 应该路由到一个 TG，而 /owner 应该路由到另一个。明确地说，我有 3 个 TG：一个在容器端口 8080 上用于 /pet，一个在容器端口 8080 上用于 /owner，另一个在容器端口 80 上用于接受 HTTP 请求。所有三个 TG 都在同一个 VPC 中。

您的 ALB 设置的 "rules" 部分对我来说似乎是个问题。它们都将模式设置为 /* ...，这意味着您不会在任何地方告诉它 /pets/* 指向一个目标而 /owners/* 指向另一个目标。
仔细查看 AWS CLI 输出后，我发现我表述的规则有误。他们都说：
"Conditions": [
{
"Field": "path-pattern",
"Values": [
"/*"
]
}
]
但是，他们应该声明：
"Conditions": [
{
"Field": "path-pattern",
"Values": [
"/pet*"
]
}
]
和
"Conditions": [
{
"Field": "path-pattern",
"Values": [
"/owner*"
]
}
]
我有一个包含 2 个模块的 Spring 项目：Pets 和 Owners，每个模块都是从单个 MySQL 数据库获取数据的微服务。当我将两者推入一个包含 2 个任务的 Docker 容器时——每个微服务 1 个——它们都启动并 运行，并且任务映射到不同的主机端口（32768 和 32769） .但是，当我转到 http://{elb-dns}/pet 时，我得到了 404，但是当我转到 http://{elb-dns}/owner 时，它 returns 预期的数据。我了解到宠物任务被映射到错误的目标组，但我不知道为什么。

我已经确认，当单独部署时，每个微服务都是独立工作的。我使用的是 Application Load Balancer，每个微服务都有自己的目标组。我不确定还有什么可以尝试或检查的。有没有人遇到过类似的问题？我还应该在哪里寻找线索？

同一个调用在 pet 任务中产生 no 日志，表明它没有被路由到容器中的正确任务。所以我仍然卡在这个问题上。
更新 2
ELB 日志显示，对于 /pet 和 /owner，所有调用都被路由到同一个目标组。但是，/pet 应该路由到一个 TG，而 /owner 应该路由到另一个。明确地说，我有 3 个 TG：一个在容器端口 8080 上用于 /pet，一个在容器端口 8080 上用于 /owner，另一个在容器端口 80 上用于接受 HTTP 请求。所有三个 TG 都在同一个 VPC 中。

您的 ALB 设置的 "rules" 部分对我来说似乎是个问题。它们都将模式设置为 /* ...，这意味着您不会在任何地方告诉它 /pets/* 指向一个目标而 /owners/* 指向另一个目标。
仔细查看 AWS CLI 输出后，我发现我表述的规则有误。他们都说：
"Conditions": [
{
"Field": "path-pattern",
"Values": [
"/*"
]
}
]
但是，他们应该声明：
"Conditions": [
{
"Field": "path-pattern",
"Values": [
"/pet*"
]
}
]
和
"Conditions": [
{
"Field": "path-pattern",
"Values": [
"/owner*"
]
}
]
