Changing the Base Domain

If you started on one base domain and want to move everything to another (say from coding9.test to my-company.test), change it in one command.

mdocker config set

mdocker config set BASE_DOMAIN my-company.test

Setting BASE_DOMAIN (or BASE_DOMAINS) is special: config set detects it and cascades the change automatically —

1. regenerates the wildcard certificate for the new domain;
2. rewrites the macOS DNS resolver at /etc/resolver/<new-domain>;
3. re-renders every project’s override with the new hostnames;
4. refreshes the edge stack.

After the switch

Restart the browser

Because a new CA / certificate is generated, restart your browser so it trusts the new wildcard cert — otherwise you may see NET::ERR_CERT_AUTHORITY_INVALID. If a specific project still routes to the old host, re-render it with mdocker rerender <name>.

Doing it by hand

If you ever edit config.env directly instead of using config set, the cascade does not run — you would need to re-run setup and re-render each project yourself:

manual re-render

mdocker setup
for n in $(mdocker --json ls | jq -r '.[].name'); do
  mdocker rerender "$n"
done

Prefer mdocker config set BASE_DOMAIN … — it does all of this for you.
