7. 踩坑记录connect: no route to host
启动容器后，在容器内访问本地mysql报错: connect: no route to host
7.1 报错信息
➜ docker-compose up WARNING: Some networks were defined but are not used by any service: backend Starting fund-server_app_1 ... done Attaching to fund-server_app_1 app_1 | panic: 创建mysql客户端失败: dial tcp 172.20.0.1:3306: connect: no route to host, {172.20.0.1 3306 root root fund_system utf8mb4 falsetrue Local 255 truefalse {falsetruefalsefalse fas_ true} 50ms info truetrue} app_1 | app_1 | goroutine 1 [running]: app_1 | 52lu/fund-analye-system/initialize.initGorm() app_1 | /build/initialize/gorm.go:50 +0x6ae app_1 | 52lu/fund-analye-system/initialize.SetLoadInit() app_1 | /build/initialize/load.go:9 +0x2f app_1 | main.main() app_1 | /build/main.go:18 +0x45 fund-server_app_1 exited with code 2
7.2 解决方法
1. 替换mysql的host
