Quartz app wasmd image

This folder contains a Dockerfile that helps build a single-node wasmd validator for use in testing your Quartz application.

It facilitates the creation of a Docker image with 4 accounts pre-loaded, each having a small amount of ucosm preloaded from genesis for experimentation.

• admin
• alice
• bob
• charlie

These accounts' details are stored in clear text in the accounts folder.

Note: this image is not intended to be used in production.

Running the image

From this directory, simply run:

make run

This will implicitly call make build to build the Docker image, and then run it, binding to the following ports on the local machine:

• 1317
• 9090
• 26656
• 26657

It also implicitly creates a Docker volume called wasmd_data such that just the contents of the /root directory in the container persist across restarts. To wipe this volume and start from scratch, simply terminate the container and run:

docker volume rm wasmd_data

Building the image

To build the image without running it, simply run:

make

This will, by default, build a Docker image tagged informaldev/wasmd:v0.44.0.

Querying accounts in the container

To query, for example, the admin account's balance, where the admin account's address is wasm1mkrm9m8g0dzv5z73xg8yzlj6srqc72qru5xfv3, once the Docker container is running, in a separate terminal run:

# The first "wasmd" indicates the name of the running Docker container, whereas
# the second "wasmd" indicates the name of the command to run inside the
# container.
docker exec -it wasmd \
    wasmd query bank balances wasm1mkrm9m8g0dzv5z73xg8yzlj6srqc72qru5xfv3

You should see output like:

balances:
- amount: "12000000000000"
  denom: ucosm
- amount: "12000000000000"
  denom: ustake
pagination:
  next_key: null
  total: "0"
