CCDScan

CCDScan is a full blockchain explorer on Concordium.

It consists of two main parts:

• backend/ Backend built in Rust. It reads data directly from a blockchain node via gRPC, ingests it into a PostgreSQL database, then serves it to any consumer from a GraphQL API.
• frontend/ A server-side rendered single page app written in Vue and TypeScript, which consumes data from the GraphQL endpoint exposed by the backend.

Releasing the docker container images:

The project contains different release pipelines.

To release a new backend docker container image:

• Create a PR that bumps the backend version in the backend/Cargo.toml file and updates the backend changelog and merge it e.g. backend release.
• Checkout the main branch locally.
• Tag the branch e.g.:

git tag ccdscan-backend/0.1.25

• Push the tag:

git push --tags

This will trigger a new release pipeline which needs to be approved before the image is published to docker hub indexer and graphQL API.

To release a new frontend docker container image:

• Create a PR that bumps the frontend version in the frontend/package.json file and updates the frontend changelog and merge it e.g. frontend release.
• Checkout the main branch locally.
• Tag the branch e.g.:

git tag frontend/1.7.7

• Push the tag:

git push --tags

This will trigger a new release pipeline which needs to be approved before the image is published to docker hub frontend.
