azure - 如何将命令传递给 terraform(Azure ACI + osm 切片服务器)

Question

我正在尝试在 Azure ACI 上设置 overv/openstreetmap-tile-server 镜像，但我不知道如何传递命令 “run” 或 “import”到容器。

例如，如果我在 terraform 代码下运行:

terraform {
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "=3.0.0"
    }
  }
}

provider "azurerm" {
  features {}
}

resource "azurerm_resource_group" "example" {
  name     = "example-resources"
  location = "West Europe"
}

resource "azurerm_storage_account" "example" {
  name                     = "storage-test"
  resource_group_name      = azurerm_resource_group.example.name
  location                 = azurerm_resource_group.example.location
  account_tier             = "Standard"
  account_replication_type = "LRS"
}

resource "azurerm_storage_share" "example" {
  name                 = "osm-data"
  storage_account_name = azurerm_storage_account.example.name
  quota                = 50
}

resource "azurerm_storage_share" "examplee" {
  name                 = "osm-tiles"
  storage_account_name = azurerm_storage_account.example.name
  quota                = 50
}


resource "azurerm_container_group" "example" {
  name                = "example-continst"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  ip_address_type     = "Public"
  dns_name_label      = "mapss11"
  os_type             = "Linux"
  restart_policy      = "Never"

  container {
    name   = "maps"
    image  = "overv/openstreetmap-tile-server"
    cpu    = "2"
    memory = "16"

    ports {
      port     = 80
      protocol = "TCP"
    }

    volume {
      name       = "osm-data"
      mount_path = "/data/database/"
      read_only  = false
      share_name = azurerm_storage_share.example.name

      storage_account_name = azurerm_storage_account.example.name
      storage_account_key  = azurerm_storage_account.example.primary_access_key
    }

      volume {
      name       = "osm-tiles"
      mount_path = "/data/tiles/"
      read_only  = false
      share_name = azurerm_storage_share.examplee.name

      storage_account_name = azurerm_storage_account.example.name
      storage_account_key  = azurerm_storage_account.example.primary_access_key
    }
  }

  tags = {
    environment = "testing"
  }
}

我可以看到以下信息:

usage: <import|run>
commands:
    import: Set up the database and import /data/region.osm.pbf
    run: Runs Apache and renderd to serve tiles at /tile/{z}/{x}/{y}.png
environment variables:
    THREADS: defines number of threads used for importing / tile rendering
    UPDATES: consecutive updates (enabled/disabled)
    NAME_LUA: name of .lua script to run as part of the style
    NAME_STYLE: name of the .style to use
    NAME_MML: name of the .mml file to render to mapnik.xml
    NAME_SQL: name of the .sql file to use

如果我将命令部分添加到terraform，例如:

terraform {
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "=3.0.0"
    }
  }
}

provider "azurerm" {
  features {}
}

resource "azurerm_resource_group" "example" {
  name     = "example-resources"
  location = "West Europe"
}

resource "azurerm_storage_account" "example" {
  name                     = "storagetestxx"
  resource_group_name      = azurerm_resource_group.example.name
  location                 = azurerm_resource_group.example.location
  account_tier             = "Standard"
  account_replication_type = "LRS"
}

resource "azurerm_storage_share" "example" {
  name                 = "osm-data"
  storage_account_name = azurerm_storage_account.example.name
  quota                = 50
}

resource "azurerm_storage_share" "examplee" {
  name                 = "osm-tiles"
  storage_account_name = azurerm_storage_account.example.name
  quota                = 50
}



resource "azurerm_container_group" "example" {
  name                = "example-continst"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  ip_address_type     = "Public"
  dns_name_label      = "mapss11"
  os_type             = "Linux"
  restart_policy      = "Never"

  container {
    name   = "maps"
    image  = "overv/openstreetmap-tile-server"
    cpu    = "2"
    memory = "16"

    commands = [
      "/bin/bash", "-c", "import"
    ]

    ports {
      port     = 80
      protocol = "TCP"
    }

    volume {
      name       = "osm-data"
      mount_path = "/data/database/"
      read_only  = false
      share_name = azurerm_storage_share.example.name

      storage_account_name = azurerm_storage_account.example.name
      storage_account_key  = azurerm_storage_account.example.primary_access_key
    }

      volume {
      name       = "osm-tiles"
      mount_path = "/data/tiles/"
      read_only  = false
      share_name = azurerm_storage_share.examplee.name

      storage_account_name = azurerm_storage_account.example.name
      storage_account_key  = azurerm_storage_account.example.primary_access_key
    }
  }

  tags = {
    environment = "testing"
  }
}

我收到此错误:

/bin/bash: line 1: import: command not found

下面你可以看到纯 docker 的样子:

docker run \
    -v osm-data:/data/database/ \
    -v osm-tiles:/data/tiles/ \
    overv/openstreetmap-tile-server \
    import 

文档:

• azurerm_container_group
• openstreetmap-tile-server

@更新:我已将命令更改为+添加了一些环境变量:

   commands = [
      "import"
    ]

  environment_variables = {
      DOWNLOAD_PBF="https://download.geofabrik.de/europe/luxembourg-latest.osm.pbf"
      DOWNLOAD_POLY="https://download.geofabrik.de/europe/luxembourg.poly"
    }

现在我得到:

Error: Failed to start container maps, Error response: to create containerd task: failed to create shim task: failed to create container 106a87f1f61033aa11ddeee2c0f6b5797157545516e1f55009c34d72ce9b50cf: guest RPC failure: failed to create container: failed to run runc create/exec call for container 106a87f1f61033aa11ddeee2c0f6b5797157545516e1f55009c34d72ce9b50cf with exit status 1: container_linux.go:380: starting container process caused: exec: "run": executable file not found in $PATH: unknown

Answer 1

你为什么不这样做:

commands = ["import"]

如果您查看 overv/openstreetmap-tile-server 图像的 Dockerfile你会发现它有入口点 /run.sh。 This script依次有以下代码:

if [ "$1" == "import" ]; then
  # ...
fi

所以 import 不是一个 shell 命令，它是一个 /run.sh 命令。
