CircleCI DynamoDB Local

问题

I'm trying to get it setup so CircleCI can use DynamoDB Local in my tests. I saw this link about how to install DynamoDB Local on CircleCI but it looks outdated since they have now moved to new syntax with CircleCI 2.

How can I achieve this on the latest versions of CircleCI?

You can adapt the old instructions into the new, using the build step 'command'. You will have to play with it a bit to get it to work as I'm not familiar with the software:

version: 2
jobs:
   build: 
     docker:
        - image: some-docker-image-that-has-java-or-even-dynamodb
     steps: 
        - stuff (usually 'checkout')  
        - run: 
           name: install java
           command: |
              apt-get update && apt-get install default-jre default-jdk
        - run:
           name: setup container
           command: |
              curl -k -L -o dynamodb-local.tgz http://dynamodb-local.s3-website-us-west-2.amazonaws.com/dynamodb_local_latest.tar.gz
              tar -xzf dynamodb-local.tgz
              java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb

Here is a working end to end circleci config.yml file that works for a nodejs project version 8 and dynamodb local:

version: 2

  container_config: &container_config
    docker:
      - image: circleci/node:8

  restore_npm_install: &restore_npm_install
    restore_cache:
      keys:

        - node_modules-v1-cache

          # Because "CredentialsError: Missing credentials in config"
