无法使用 Project Tye 与 Docker 容器中的 SQL 服务器 运行 建立连接
Cannot establish connection to a SQL server running in Docker container using Project Tye
我对微服务架构的整个概念相当陌生，但我已经设法创建了一个简单的概念验证应用程序，它由 1 个 Blazor 服务器端前端、6 个微服务组成，它们都是.net 6 WEB API，目前正在使用 InMemory 数据库，它们都在启动时将模拟数据播种到它们的数据库中。
我正在使用 Project Tye 同时 运行 所有项目并轻松将它们部署到本地 kubernetes 集群。
现在我想将每个微服务的上述 InMemory 数据库迁移到 sql 服务器数据库。
Tye 允许 运行 图像作为 tye.yaml 文件中的依赖项并从配置中设置环境变量，然后通过 Tye 的 VS 扩展作为 ConnectionString 配置。
这是其中关于一个 sql 服务器的片段：
- name: sqlserver-videoteka
image: mcr.microsoft.com/mssql/server:2019-latest
env:
- name: SA_PASSWORD
value: "M!cr0s3rv!ce"
- name: ACCEPT_EULA
value: 'Y'
volumes:
- name: videoteka-storage
target: /var/opt/mssql
bindings:
- port: 9634
connectionString: Server=${host}:${port};Database=VideotekaDB;MultipleActiveResultSets=true;User Id=sa;Password=${env:SA_PASSWORD};
然后在微服务的 Program.cs 文件中添加这两行：
connectionString = configuration.GetConnectionString("sqlserver-videoteka");
builder.Services.AddDbContext<VideotekaDbContext>(options => options.UseSqlServer(connectionString));
然后我尝试 运行 tye 运行 并检查来自上述微服务的日志，这就是我遇到的：

据我了解 Tye 的配置，它会创建 sql 服务器的映像并使用我的变量作为凭据，不是吗？
单独的 sql 服务器容器是否需要 运行 在我的机器上？但是为什么它会拉取镜像并创建一个容器呢？
非常感谢任何帮助。谢谢。
编辑：CER 为我解决了关于 tye 运行 的问题，但是当 运行ning tye deploy，sql服务器被跳过？
这发生在部署结束时。
我认为可能有两个问题：
- 您的
bindings 部分应包含 containerPort:1433 以映射到 9643。参见 tye schema。
- 回复：
connectionstring。 SQL 主机和端口之间的服务器分隔符 不是 冒号 (:)，而是逗号 (,)。例如localhost,9643.
