# Docker 离线部署包（${APP_NAME} ${VERSION}）
|
||||
|
||||
## 包含内容
|
||||
- 应用镜像：${APP_IMAGE}
|
||||
- pgvector 数据库镜像：${PGVECTOR_IMAGE}
|
||||
- Redis 缓存镜像：${REDIS_IMAGE}
|
||||
- docker-compose.yml / .env / config / pgvector-init 目录
|
||||
|
||||
## 使用步骤
|
||||
1. 将整个目录拷贝到目标服务器并进入该目录：
|
||||
\`\`\`
|
||||
cd $(basename "${OUTPUT_DIR}")
|
||||
\`\`\`
|
||||
2. 导入离线镜像：
|
||||
\`\`\`
|
||||
docker load -i images/app-${VERSION}.tar
|
||||
docker load -i images/pgvector.tar
|
||||
docker load -i images/redis.tar
|
||||
\`\`\`
|
||||
3. 根据需要修改 \`.env\`、\`config/application.yml\`。
|
||||
4. 启动：
|
||||
\`\`\`
|
||||
docker compose up -d
|
||||
\`\`\`
|
||||
5. 查看状态：
|
||||
\`\`\`
|
||||
docker compose ps
|
||||
docker compose logs -f app
|
||||
\`\`\`
|
||||
|
||||
缺省账号密码可通过执行脚本前设置环境变量覆盖，如：
|
||||
\`\`\`
|
||||
POSTGRES_PASSWORD=StrongPass REDIS_PASSWORD=Secret ./build-docker-bundle.sh
|
||||
\`\`\`
|
||||

|
||||

|

||||
docker save "${PGVECTOR_IMAGE}" -o "${IMAGES_DIR}/pgvector.tar"
|
