Docker

It is possible to use CloudQuery in an isolated container. You can pull the relevant image via docker pull ghcr.io/cloudquery/cloudquery:latest.

Configuration

Create a Config File on the Host Machine

CloudQuery uses YAML files as the primary means of configuration. A simple example config.yml file would look like:

kind: source
spec:
  name: aws
  path: cloudquery/aws
  version: "v9.0.1"
  tables: ["aws_ec2_*"]
  destinations: ["postgresql"]
---
kind: destination
spec:
  name: postgresql
  path: cloudquery/postgresql
  version: "v2.0.0"
  spec:
    connection_string: "postgres://postgres:pass@host.docker.internal:5432/postgres?sslmode=disable"

Run the Container

For the CloudQuery docker container to use this configuration file you will need to mount the volume to the container like so:

docker run --pull always \
  -v <ABSOLUTE_PATH_TO_CONFIG_FILE>:/config.yml \
  # set any env variable with -e <ENV_VAR_NAME>=<ENV_VAR_VALUE>
  ghcr.io/cloudquery/cloudquery:latest \
  sync /config.yml

As with running any cloudquery command on your CLI you can override the config with the optional flags with the docker container. You will also need to make sure you load any ENV variables for source and destination plugins, such as your AWS_* keys etc.

If you split the configuration between multiple files, you can mount the directory containing them, instead of just the config.yml file.

If you are running Docker on an ARM Apple device and you see a segmentation fault when running the container like so qemu: uncaught target signal 11 (Segmentation fault) - core dumped; please make sure you are running the latest Docker for Mac release.

Caching

Due to the way cloudquery is designed it downloads all the components to interact with source and destination plugins. This means that with a docker container it runs the download step each time, as the local cache is lost between executions. To avoid this we recommend mounting a volume to cache the data and configuring cloudquery to use this via the --cq-dir optional flag. An example of this would be:

docker run --pull always \
  -v <ABSOLUTE_PATH_TO_CONFIG_FILE>:/config.yml \
  -v <ABSOLUTE_PATH_TO_CACHE_DIRECTORY>:/cache/.cq \
  # set any env variable with -e <ENV_VAR_NAME>=<ENV_VAR_VALUE>
  ghcr.io/cloudquery/cloudquery:latest \
  sync /config.yml --cq-dir /cache/.cq

Depending on your operating system, the built components maybe different between your local system and the container. To avoid the different please use a separate cache directory for the container than a local instance of cloudquery.
