docker - OpenMapTiles docker 无法使用之前的配置启动

Question

我创建了一个 OpenMapTiles 容器:

• 使用 /data 目录的卷
• 使用图像klokantech/openmaptiles-server:1.6。

容器启动良好。我下载了星球文件。而且服务运行良好。

因为我要把它推向生产:如果容器死机，我的编排系统(Kubernetes)将自动重新启动它，我希望它选择以前的配置(所以它不需要再次下载行星文件或设置任何配置)。

所以我杀死了我的容器并使用之前的相同卷重新启动它。

问题:当我的容器重新启动时，我重新启动的 MapTiles 没有以前的配置，并且我在 UI 中收到此错误:

OpenMapTiles Server is designed to work with data downloaded from OpenMapTiles.com, the following files are unknown and will not be used: osm-2018-04-09-v3.8-planet.mbtiles

此外，我的日志显示:

我想可能是配置中的未定义导致了问题:

Existing configuration found in /data/config.json Data file "undefined" not found!

这是我的配置文件:

 root@maptiles-0:/#  cat /data/config.json
 {
   "styles": {
     "standard": [
       "dark-matter",
       "klokantech-basic",
       "osm-bright",
       "positron"
     ],
     "custom": [],
     "lang": "",
     "langLatin": true,
     "langAlts": true
   },
   "settings": {
     "serve": {
       "vector": true,
       "raster": true,
       "services": true,
       "static": true
     },
     "raster": {
       "format": "PNG_256",
       "hidpi": 2,
       "maxsize": 2048
     },
     "server": {
       "title": "",
       "redirect": "",
       "domains": []
     },
     "memcache": {
       "size": 23.5,
       "servers": [
         "localhost:11211"
       ]
     }
   }

我应该在其他地方安装新卷吗？我应该更改我的 /data/config.json 吗？我不知道如何使它可以被杀死

我使用图像 klokantech/tileserver-gl:v2.3.1 修复了此问题。通过此图像，您可以下载 MBTiles 文件形式的矢量切片 OpenMapTiles Downloads

您可以在此处找到说明:https://openmaptiles.org/docs/host/tileserver-gl/

另外:我使用以下 StatefulSet 将其部署到 kubernetes:

apiVersion: apps/v1beta1
kind: StatefulSet
metadata:
  labels:
    name: maptiles
  name: maptiles
spec:
  replicas: 2
  selector:
    matchLabels:
      name: maptiles
  serviceName: maptiles
  template:
    metadata:
      labels:
        name: maptiles
    spec:
      containers:
      - name: maptiles
        command: ["/bin/sh"]
        args:
        - -c
        - |
          echo "[INFO] Startingcontainer"; if [ $(DOWNLOAD_MBTILES) = "true" ]; then
            echo "[INFO] Download MBTILES_PLANET_URL";
            rm /data/*
            cd /data/
            wget -q -c $(MBTILES_PLANET_URL)
            echo "[INFO] Download finished";
          fi; echo "[INFO] Start app in /usr/src/app"; cd /usr/src/app && npm install --production && /usr/src/app/run.sh;
        env:
        - name: MBTILES_PLANET_URL
          value: 'https://openmaptiles.com/download/W...'
        - name: DOWNLOAD_MBTILES
          value: 'true'
        livenessProbe:
          failureThreshold: 120
          httpGet:
            path: /health
            port: 80
            scheme: HTTP
          initialDelaySeconds: 10
          periodSeconds: 30
          successThreshold: 1
          timeoutSeconds: 5
        ports:
        - containerPort: 80
          name: http
          protocol: TCP
        readinessProbe:
          failureThreshold: 120
          httpGet:

            scheme: HTTP
          initialDelaySeconds: 10
          periodSeconds: 30
          successThreshold: 1
          timeoutSeconds: 5
        resources:
          limits:
            cpu: 500m
            memory: 4Gi
          requests:
            cpu: 100m
            memory: 2Gi
        volumeMounts:
        - mountPath: /data
          name: maptiles
  volumeClaimTemplates:
  - metadata:
      creationTimestamp: null
      name: maptiles
    spec:
      accessModes:
      - ReadWriteOnce
      resources:
        requests:
          storage: 60Gi
      storageClassName: standard

我首先使用 DOWNLOAD_MBTILES='true' 部署它，然后将其更改为 DOWNLOAD_MBTILES='false' (因此下次它不会清理 map )已部署)。

我测试了它，当它有 DOWNLOAD_MBTILES='false' 时，您可以终止容器，它们会在一分钟左右重新启动。
