elasticsearch-countries-and-capitals data

This repository hosts the data preloaded in the deepset/elasticsearch-countries-and-capitals Docker image, recovered using elasticsearch-dump. The name of the Elasticsearch index for the above container is document.

Building the container

As a prerequisite step, download the Node.js LTS v16.16.0 Linux binaries into the local directory, the Docker context:

$ wget https://nodejs.org/dist/v16.16.0/node-v16.16.0-linux-x64.tar.xz

Why do this? To take advantage of xz decompression that ADD does automatically for local files. Alternatively, this could be handled by chaining curl and tar in the Dockerfile, but that requires xz be in the image. This approach may ultimately be preferred, but to keep the image size small, would require a multi-stage build.

Run docker build and tag appropriately:

$ docker build -t <tag> .
