```go
package custom

import (
    "text/template"
    "bytes"

    "github.com/spf13/afero"
    "github.com/zeabur/zbpack/pkg/packer"
    "github.com/zeabur/zbpack/pkg/plan"
    "github.com/zeabur/zbpack/pkg/types"
)

type customPacker struct {
    *customIdentify
}

// NewPacker returns a new custom packer
func NewPacker() packer.Packer {
    return &customPacker{
        customIdentify: &customIdentify{},
    }
}

// GenerateDockerfile generates a Dockerfile for this project type
func (p *customPacker) GenerateDockerfile(meta types.PlanMeta) (string, error) {
    dockerfileTemplate := `FROM ubuntu:22.04

WORKDIR /app
ENV PORT=8080

# Install dependencies

    curl \
    && rm -rf /var/lib/apt/lists/*

COPY . .

# Install project dependencies
RUN {{ .InstallCmd }}

# Build the project
{{ if .BuildCmd }}RUN {{ .BuildCmd }}{{ end }}

EXPOSE 8080
CMD {{ .StartCmd }}
`

    tmpl, err := template.New("dockerfile").Parse(dockerfileTemplate)
    if err != nil {
        return "", err
    }

    data := struct {
        InstallCmd string
        BuildCmd   string
        StartCmd   string
    }{
        InstallCmd: meta["installCmd"],
        BuildCmd:   meta["buildCmd"],
        StartCmd:   meta["startCmd"],
    }

    var buf bytes.Buffer
    if err := tmpl.Execute(&buf, data); err != nil {

    }

    return buf.String(), nil
}

var _ packer.Packer = (*customPacker)(nil)
```

### Generate and Inject into Dockerfile with zeaburpack

Source: https://context7.com/zeabur/zbpack/llms.txt

Generates a Dockerfile based on a determined plan type and metadata. It can also inject user-defined environment variables and a proxy registry into the generated Dockerfile.

```go
package main

import (
    "fmt"
    "log"

    "github.com/zeabur/zbpack/pkg/zeaburpack"
    "github.com/zeabur/zbpack/pkg/types"
)

func main() {
    // Generate Dockerfile from plan
    dockerfile, err := zeaburpack.GenerateDockerfile(&zeaburpack.GenerateDockerfileOptions{
        PlanType: types.PlanTypeNodejs,
        PlanMeta: types.PlanMeta{
            "nodeVersion":    "20",
            "packageManager": "pnpm",
            "framework":      "next.js",
            "installCmd":     "pnpm install",
            "buildCmd":       "pnpm build",
            "startCmd":       "pnpm start",
            "outputDir":      "",  // empty for server-side apps
        },
    })

    if err != nil {
        log.Fatalf("Failed to generate Dockerfile: %v", err)
    }

    fmt.Println(dockerfile)

    // Inject environment variables and registry into Dockerfile
    userVars := map[string]string{
        "NODE_ENV": "production",
        "API_URL": "https://api.example.com",
    }
    proxyRegistry := "docker.io"

    injectedDockerfile := zeaburpack.InjectDockerfile(dockerfile, &proxyRegistry, userVars)
    fmt.Println(injectedDockerfile)
}
```

### Custom Identifier Implementation in Go

Source: https://context7.com/zeabur/zbpack/llms.txt

Implement custom language or framework identifiers by implementing the `plan.Identifier` interface. The `Match` method checks for project markers like `custom.config.json` or `.customrc`.

```go
package custom

import (
    "github.com/spf13/afero"
    "github.com/zeabur/zbpack/internal/utils"
    "github.com/zeabur/zbpack/pkg/plan"
    "github.com/zeabur/zbpack/pkg/types"
)

type customIdentify struct{}

// NewIdentifier returns a new custom identifier
func NewIdentifier() plan.Identifier {
    return &customIdentify{}
}

// PlanType returns the plan type this identifier handles
func (i *customIdentify) PlanType() types.PlanType {
    return types.PlanType("custom")
}

// Match returns true if this identifier matches the project
func (i *customIdentify) Match(fs afero.Fs) bool {
    // Check for custom framework markers
    return utils.HasFile(fs, "custom.config.json") ||
           utils.HasFile(fs, ".customrc")
}

// PlanMeta returns the build metadata for this project
func (i *customIdentify) PlanMeta(options plan.NewPlannerOptions) types.PlanMeta {
    src := options.Source
    config := options.Config

    // Read custom configuration
    meta := types.PlanMeta{
        "framework": "custom-framework",
    }

    // Check for user overrides
    if installCmd, err := plan.Cast(
        config.Get(plan.ConfigInstallCommand),
        cast.ToStringE,
    ).Take(); err == nil {
        meta["installCmd"] = installCmd
    } else {
        meta["installCmd"] = "custom install"
    }

    if buildCmd, err := plan.Cast(
        config.Get(plan.ConfigBuildCommand),
        cast.ToStringE,
    ).Take(); err == nil {
        meta["buildCmd"] = buildCmd
    } else {
        meta["buildCmd"] = "custom build"
    }

    meta["startCmd"] = "custom start"

    return meta
}

var _ plan.Identifier = (*customIdentify)(nil)
```

### Output Generated Dockerfile

Source: https://context7.com/zeabur/zbpack/llms.txt

Generates and outputs the Dockerfile for the project without building the image. Use `--dockerfile` or `-d`.

```bash
./zbpack --dockerfile /path/to/project
```

```bash
./zbpack -d /path/to/project
```
