Docker 验证证据

NATS 已验证 · Verified 🕒 快照采集: 2026-08-23 15:19:49 UTC

官方镜像为 distroless，仅有 nats-server；nats CLI 独立发行，不伪装成镜像自带能力。

🐳 镜像:server:nats:2.11.5

🛠️ 关键工具:nats-server

🔨 构建/检查无镜像内建队列/主题 CLI

🚀 运行/交互8222 /healthz、/varz、/connz、/subsz

## status
[cli-tools] $ curl -fsS http://127.0.0.1:8222/healthz
{"status":"ok"}

## gap
# 缺口记录：nats 官方镜像不含 nats CLI（由 nats-io/natscli 独立发行），distroless 镜像连 shell 都没有，
# 纯镜像自带命令无法收发消息；收发需外部客户端（Java 实验见 demos/nats/core-pubsub）。
[cli-tools] $ compose exec nats nats --version   # 尝试在容器内寻找自带 CLI，预期失败
OCI runtime exec failed: exec failed: unable to start container process: exec: "nats": executable file not found in $PATH
exit=127（预期失败：镜像不含 nats 二进制）
