chore(dockerhub): migrate namespace zkcoin → zkcoins - #96
Merged
Conversation
Aligns Docker Hub namespace with the rest of the project identity:
GitHub org `zk-coins`, domain `zkcoins.app`, Cargo workspace member
`node` already use the plural form; the singular `zkcoin/*` namespace
was a holdover from the early days.
Touched:
- .github/workflows/deploy-{dev,prd}.yaml — DOCKER_TAGS + cache refs
- Dockerfile — comment header (build/run examples)
- README, CONTRIBUTING, ROADMAP, MIGRATION_RESEARCH — image refs
Coordinated DFXServer/server compose update follows immediately after
merge so dfxdev / dfxprd pull the new `zkcoins/node:{beta,latest}`.
The legacy `zkcoin/node` repo on Docker Hub stays as a deprecated
read-only mirror.

Why
The Docker Hub namespace was `zkcoin/` (singular) while the rest of
the project identity uses the plural form:
`zkcoin/` was a leftover. Migrating now while we're already doing the
identity rename minimises churn.
What
Replaces every `zkcoin/node` and `zkcoin/server` reference in this
repo with `zkcoins/node`:
Repo secrets `DOCKER_USERNAME` / `DOCKER_PASSWORD` already point at the
new `zkcoins` Docker Hub account (set ahead of this PR — that's why
the post-#93 `Deploy DEV` failed with `insufficient_scope` on
`zkcoin/node:beta`).
Coordinated follow-ups
`image:` lines + READMEs — pushed by me immediately after this PR merges.
pointer; final deprecation notice + last-tag freeze is Phase 9 of
the rename rollout.
Test
namespace (creds match), then SSH to dfxdev runs `zkcoins-node`,
`deploy.sh` accepts it, but `docker compose pull` needs the
DFXServer/server compose update (separate push) to point at the new
image — which I'll push as soon as the new image lands on Docker Hub.
