如何修复 headscale 启动错误 failed to configure TLS (sslmode is invalid)
问题：
启动 headscale 0.17.0 或更新版本时，你看到重复的错误消息如
headscale-error.txt
headscale_1 | 2022-11-26T20:03:39Z FTL go/src/headscale/cmd/headscale/cli/server.go:21 > Error initializing error="cannot parse `host=postgres dbname=headscale user=headscale sslmode= port=5432 password=xxxxx`: failed to configure TLS (sslmode is invalid)"解决方案
此错误由于从 headscale 0.17.0 开始的更改而发生。在你的 config.yaml 中，添加
db_ssl: false
config.yaml
db_ssl: false在 db_type: ... 之后
完整数据库部分配置示例：
config.yaml
# # Postgres 配置
db_type: postgres
db_host: postgres
db_port: 5432
db_name: headscale
db_user: headscale
db_pass: Paep6AhJiZeedie5fiefieV0quohro
db_ssl: false之后，重启 headscale，错误消息应该消失。
