What’s New in Nacos 0.8.0? Key Features, Installation & First‑Run Guide
The article introduces Nacos 0.8.0, highlighting its three major production features—user login, Prometheus metrics, and namespace isolation—while providing step‑by‑step download links, startup commands for Linux and Windows, and instructions to access the default login console.
Last night the Nacos community released its first production‑grade version 0.8.0, which besides bug fixes adds three crucial production features.
Reasons for the upgrade
According to the official release notes, version 0.8.0 supports:
User login . Previously Nacos could be accessed without authentication; the new version provides built‑in login control.
Prometheus support . Metrics are exposed at the /prometheus endpoint for monitoring the Nacos cluster.
Namespace support . Service discovery can be isolated by namespace, enabling multi‑environment isolation on a single cluster.
Installation and usage
Replace the Nacos installation package with the 0.8.0 tarball:
Download: https://github.com/alibaba/nacos/releases/download/0.8.0/nacos-server-0.8.0.tar.gz
After extracting, run the appropriate startup script:
Linux/Unix/Mac: sh startup.sh -m standalone Windows: cmd startup.cmd -m standalone The startup.sh (or startup.cmd) script resides in the bin directory of the extracted package.
Once started, open http://127.0.0.1:8848/nacos/ to reach the login page. The default username and password are nacos. After logging in you will see the console.
No code changes are required on the client side to adapt to the new version.
