LetвЂ™s say you have a webapp written in Java running in a tomcat container and you want to access the local dynamo db container for your integration tests.

#Sam local dynamodb driver#

docker-compose upДЄws dynamodb list-tables -endpoint-url If youвЂ™re not using the default network mode and instead using bridge network mode, this is how your docker compose will look like: version : ' 2' services : dynamodb : image : amazon/dynamodb-local:latest ports : - ' 8000:8000' command : networks : test-network : ipv4_address : 172.16.231.1 networks : test-network : driver : bridge driver_opts : _ipv6 : ' false' ipam : driver : default config : - subnet : 172.16.231.0/24 gateway : 172.16.231.1ДЄccessing DynamoDB Local Container From Another Container

Run docker compose and access your local dynamo db by using the endpoint url option in your CLI commands. Table created via your CLI wonвЂ™t be visible to your app container. If you didnвЂ™t enable this setting then if in case your app container and local CLI use different AWS creds then they wonвЂ™t be accessing the same dynamo db state. This is to ensure that the dynamo db uses a single database file instead of separate files for each credential and region. We override the command here with an additional argument -sharedDb. We pull the latest version of amazon/dynamodb-local imageД®xpose the container port 8000 to local port 8000 as the local dynamo db runs on this portД«y default the local dynamo db starts with inMemory setting. version : ' 2' services : dynamodb : image : amazon/dynamodb-local:latest ports : - ' 8000:8000' command : WeвЂ™ll create a docker compose file to launch dynamo db local as a container which can then be accessed by other containers.

The new Docker image also enables you to include DynamoDB local in your containerized builds and as part of your continuous integration testing.
