Kratos Project Template

Install Kratos

go install github.com/go-kratos/kratos/cmd/kratos/v2@latest

Create a service

# Create a template project
kratos new server

cd server
# Add a proto template
kratos proto add api/server/server.proto
# Generate the proto code
kratos proto client api/server/server.proto
# Generate the source code of service by proto file
kratos proto server api/server/server.proto -t internal/service

go generate ./...
go build -o ./bin/ ./...
./bin/server -conf ./configs

Generate other auxiliary files by Makefile

# Download and update dependencies
make init
# Generate API files (include: pb.go, http, grpc, validate, swagger) by proto file
make api
# Generate all files
make all

Automated Initialization (wire)

# install wire
go get github.com/google/wire/cmd/wire

# generate wire
cd cmd/server
wire

Docker

# build
docker build -t <your-docker-image-name> .

# run
docker run --rm -p 8000:8000 -p 9000:9000 -v </path/to/your/configs>:/data/conf <your-docker-image-name>

Ent

在 data 目录下运行以下命令初始化 scheme

go run -mod=mod entgo.io/ent/cmd/ent new User

上面的命令将在 entdemo/ent/schema/ 目录下为 User 生成架构：

//entdemo/ent/schema/user.go
package schema

import "entgo.io/ent"

// User holds the schema definition for the User entity.
type User struct {
    ent.Schema
}

// Fields of the User.
func (User) Fields() []ent.Field {
    return nil
}

// Edges of the User.
func (User) Edges() []ent.Edge {
    return nil
}

将 2 个字段添加到 User 架构：

package schema

import (
    "entgo.io/ent"
    "entgo.io/ent/schema/field"
)

// Fields of the User.
func (User) Fields() []ent.Field {
    return []ent.Field{
        field.Int("age").
            Positive(),
        field.String("name").
            Default("unknown"),
    }
}

从项目的date目录运行 go generate ，如下所示：

go generate ./ent

这将生成以下文件：
