Supported Environments

简体中文 | English

Center

The Center is supported on Linux with Docker Engine and Docker Compose. Release gates validate it with a 512 MiB memory limit. One Center container serves both the API and the web administration interface.

The Center needs outbound HTTPS access to GitHub for release discovery. It does not terminate TLS or configure a reverse proxy.

Agent

The root Agent supports these AMD64 and ARM64 environments:

• Debian 12 and 13;
• Ubuntu 24.04 and 26.04;
• RHEL, Rocky Linux, and AlmaLinux 8, 9, and 10;
• CentOS Stream 9 and 10; and
• Alpine Linux 3.23 and 3.24 with OpenRC.

The installer rejects other operating systems, distribution releases, architectures, and init systems. Complete probes are validated with a 64 MiB memory limit. Below 64 MiB, the Agent continues observing public addresses but automatically pauses complete probes. An administrator may explicitly override that pause in the node settings.

An Agent needs outbound HTTP or HTTPS access to:

• the Center;
• configured public-IP discovery services;
• official GitHub Releases used for installation and updates; and
• third-party databases, streaming services, AI services, DNSBLs, and mail services used by complete probes.

A node proxy applies only to explicitly configured proxy egresses on that node. It is not a global proxy for the Center or Agent.
