CircleCI script to test against DynamoDB Local Fails - amazon-web-services

Question

We have a CircleCI script that manages our deployment. I wanted to allow DynamoDB local to run so that we could test our DynamoDB requests. I've tried following the answers here, here and here. I've also tries using the DynamoDB local image from Docker Hub, here. This is the closest I've gotten.
version: 2
jobs:
setup-dynamodb:
docker:
- image: openjdk:15-jdk
steps:
- setup_remote_docker:
version: 18.06.0-ce
- run:
name: run-dynamodb-local
background: true
shell: /bin/bash
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 -port 8000 -sharedDb

tar -C /usr/local/bin -xzvf dockerize-linux-amd64-$DOCKERIZE_VERSION.tar.gz && \
rm dockerize-linux-amd64-$DOCKERIZE_VERSION.tar.gz
environment:
DOCKERIZE_VERSION: v0.3.0
- run:
name: Wait for Local DynamoDB
command: dockerize -wait tcp://localhost:8000 -timeout 1m
- run:
name: checkerr
shell: /bin/bash
command: |
ls -laF /tmp/app/workspace/
for i in $(seq 1 2); do
f=$(printf "failed%d.txt" $i)
value=$(</tmp/app/workspace/$f)
if [[ "$value" != "nil" ]]; then
echo "$f = $value"
exit 1
fi
done
The problem I'm having is that all my tests are failing with error message dial tcp 127.0.0.1:8000: connect: connection refused. I'm not sure why this is happening. Do I need to expose the port from the container?

Answer 1

The reason is, the first job is totally seperate to second job.
In fact, you don't need the first one, and adjust second one as below
check-failed:
docker:
- image: golang:1.14.3
- image: amazon/dynamodb-local
steps:
- setup_remote_docker:
...
...
By the way, you don't need install dynamodb every time, you can run as container as well
