AWS MWAA：嘗試在 Docker 上運行本地 Apache Airflow 環境時出現“無法訪問 Postgres”錯誤

Question

按照適用於 Windows 的AWS MWAA（Amazon Managed Workflows for Apache Airflow）安裝教程使用 WSL（Linux 的 Windows 子系統）2 中的 Docker 和 Ubuntu 發行版，我在嘗試運行本地 Apache Airflow 環境時遇到了問題。

當我輸入命令wsl ./mwaa-local-env start ，輸出如下：

docker-postgres-1      | chmod: /var/lib/postgresql/data: Operation not permitted
docker-postgres-1      | The files belonging to this database system will be owned by user "postgres".

Answer 1

該解決方案為我修復了它：

1. docker volume create --name=db-data在 docker 中創建一個db-data卷

2. 在文件./docker/docker-compose-local.yml更改行

   - "${PWD}/db-data:/var/lib/postgresql/data"

   至

   - "/db-data:/var/lib/postgresql/data"
