Cannot access Terrain Server for Cesium

Question

I'm trying to follow a series of tutorials:

visualizing-terrains-with-cesium-ii

visualizing-terrains-with-cesium

Some other useful posts here:

Unable to serve Cesium Terrain files

error-in-loading-terrain-files-terrain

Basically, I want to use my own terrain files within Cesium.

I'm stack in configuring the terrain server aspect,

I have a Node.js server running Cesium Apps in port 8080: http://localhost:8080/Apps/own_terrain.html

Path for the html file is:

C:/Users/username/Downloads/software/Cesium-1.53/Apps/own_terrain.html

The terrain files have been generated by using: cesium-terrain-builder-docker

Then, I want to run my terrain tiles using cesium-terrain-server in docker.

This is how I built it:

docker run -p 9000:8080 -v C:/Users/username/Downloads/software/Cesium-1.53/Apps/terrain:/data/tilesets/terrain \
geodata/cesium-terrain-server

So, Cesium running in 8080 and terrain server in 9000,

However when I try to access the terrain tiles, i.e:

http://localhost:9000/tilesets/tiles/0/0/0.terrain

Nothing happens, Chrome says:

localhost didn’t send any data. ERR_EMPTY_RESPONSE

And the same when integrating that into the own_terrain.html:

Cesium.js:445 GET http://localhost:9000/tilesets/tiles/layer.json net::ERR_EMPTY_RESPONSE

Definitely the terrain server is not running. What am I missing in these tutorials?

Answer 1

I know it is super old but faced a similar issue.

Turns out, the cesium-terrain-server was listening to Port 8000 inside docker. I verified it by running the image in interactive mode

docker run -p 4000:80 --rm -v $PWD:/data/tilesets/terrain -it --env WEB_DIR=/data/tilesets/terrain/ geodata/cesium-terrain-server bash

I mapped port 4000 to 80 in the beginning because the documentation instructed me to do so.

Then I ran cesium-terrain-server inside the docker and received:

NOTICE: server listening on port 8000

So, I just mapped my port 4000 to 8000 and it started serving the terrain tiles.

After Comment Suggestion

I was asked to also include how I mapped port 4000 to 8000. Here is how I did it.

docker run -p 4000:8000 --rm -v $PWD:/data/tilesets/terrain -it --env WEB_DIR=/data/tilesets/terrain/ geodata/cesium-terrain-server bash
