deploy

Docker1.13推出了一个新版本的Docker Compose（V3）。该版本的主要特征是，允许Swarm Mode使用Docker Compose文件定义直接部署服务。

定义compose-file

[root@swarm-manager ~]# cat docker-compose.yml 
version: '3'
services:
  mysql:
    image: mysql
    environment:
      - MYSQL_ROOT_PASSWORD=password
  wordpress:
    image: wordpress
    ports:
      - 80:80
    links:
      - mysql:mysql
    environment:
      - WORDPRESS_DB_PASSWORD=password

在Swarm Mode下，需要使用docker stack deploy命令进行部署，如果直接使用docker-compose up则将会出现如下警告：

[root@swarm-manager ~]# docker-compose up
WARNING: The Docker Engine you're using is running in swarm mode.

Compose does not use swarm mode to deploy services to multiple nodes in a swarm. All containers will be scheduled on the current node.

To deploy your application across the swarm, use `docker stack deploy`.

通过compose-file部署多个Service

理解 OpenStack Swift （1）：OpenStack + 三节点Swift 集群+ HAProxy + UCARP 安装和配置

本系列文章着重学习和研究OpenStack Swift，包括环境搭建、原理、架构、监控和性能等。（1）OpenStack + 三节点Swift 集群+ HAProxy + UCARP 安装和配置（2）原理、架构和性能（3）监控要实现的系统的效果图：特点：使用三个对等物理节点，每个节点上部署所有Swift 服务使用开源的 UCARP 控制一个 VIP，它会被绑定到三个物理网卡中的一个。使用开源的 HAProxy 做负载均衡开启 Swift TempURL 1. Swift 集群安装和配置 1.1 Swift 安装 Swift 是被设计来在商用硬件上运行的。而且在存储磁盘上不需要而且不推荐使用RAID，相反，使用 RAID 5 或者 6 的和，会带来严重的性能下降。Swift 中包含多种服务，主要的有四种： Proxy Services Object Services Container Services Account Services 这些服务都可以独立运行。这些服务中，Proxy service 是更需要 CPU 和网络带宽的，因此，可以使用 10GbE...

简述此文档以XXXLogApi-nj项目为例，讲解了将基于Node.js+Express开发的javascript项目容器化的过程。希望以后类似的项目可以以此为参照进行扩展。 XXXLogApi-nj本身是一个微服务化的项目，其作用是为系统单纯的收集相关发布日志，以便能及时的展示给用户。 ***这份文档的操作，开始于编码完成之后流程。不涉及GIT和JENKINS的等的操作。 ***为保持职业操作，涉及公司信息的地方作了敏感化处理。 ***在这个系列中，我同时作了spring boot, beego, django, node.js框架的容器化操作，大同小异，故而只列出第一篇吧。步骤整个项目的操作过程如下： ä¸ï¼ 开发好业务代码，并且测试通过。由于javascript为解释型语言，将开发好的目录先移至制作目录下二，下载好基础镜像,为减小镜像，基础镜像为node:9.0.0-alpine,并上传到harbor仓库。三，编写dockerfile并生成项目镜像。 Dockerfile文件内容 FROM 1.2.3.4/public/node:9.0.0-alpine ...
