docker-compose 部署lakefs使用外部postgressql数据库时报错 failed to connect to `host=/tmp user=lakefs database=`:

time="2024-01-07T14:26:46Z" level=info msg="lakeFS run" func=cmd/lakefs/cmd.glob..func8 file="cmd/run.go:91" version=1.6.0
time="2024-01-07T14:26:46Z" level=fatal msg="Failed to open KV store" func=cmd/lakefs/cmd.glob..func8 file="cmd/run.go:99" error="connect failed: failed to connect to `host=/tmp user=lakefs database=`: dial error (dial unix /tmp/.s.PGSQL.5432: connect: no such file or directory)"
 

解决方案：

在yaml文件中加入

 - LAKEFS_DATABASE_TYPE=postgres
 - LAKEFS_DATABASE_POSTGRES_CONNECTION_STRING=postgres://postgres:postgres@postgres/postgres?sslmode=disable

推荐配置的docker-compose.yml， 但个人还是喜欢独立的部分，各部分分开部署。
