用tsuru部署Go应用

概述

在tsuru中创建应用

使用命令创建应用：

对于Go来说，应用平台是Go！让我们脑洞大开，开发一个’hello world‘教学应用，让我们叫它helloworld：

  1.     $ tsuru app-create helloworld go

使用platform-list命令列出所有的可用的平台。使用app-list查看你所有的应用。

  1.     $ tsuru app-list
  2.     +-------------+-------------------------+--------------------------------+
  3.     | Application | Units State Summary     | Address                        |
  4.     +-------------+-------------------------+--------------------------------+
  5.     | helloworld  | 0 of 0 units in-service | helloworld.192.168.50.4.nip.io |
  6.     +-------------+-------------------------+--------------------------------+

应用的代码

用Go实现的一个简单web应用main.go：

通过Git部署

  1.     $ tsuru app-info --app helloworld
  2.     Application: helloworld
  3.     Repository: git@192.168.50.4.nip.io:helloworld.git
  4.     Platform: go
  5.     Teams: admin
  6.     Address: helloworld.192.168.50.4.nip.io
  7.     Owner: admin@example.com
  8.     Team owner: admin
  9.     Pool: theonepool
  11.     App Plan:
  12.     +---------------+--------+------+-----------+--------+---------+
  13.     | Name          | Memory | Swap | Cpu Share | Router | Default |
  14.     +---------------+--------+------+-----------+--------+---------+
  15.     | autogenerated | 0 MB   | 0 MB | 100       |        | false   |
  16.     +---------------+--------+------+-----------+--------+---------+

Git远程分支被用来通过Git部署应用。当修改被推送到tsuru远程分支时，项目同时也被部署：

  1.     $ git push git@192.168.50.4.nip.io:helloworld.git master
  2.     Counting objects: 3, done.
  3.     Delta compression using up to 4 threads.
  4.     Compressing objects: 100% (2/2), done.
  5.     Writing objects: 100% (3/3), 430 bytes | 0 bytes/s, done.
  6.     Total 3 (delta 0), reused 0 (delta 0)
  7.     remote: tar: Removing leading `/' from member names
  8.     remote: /
  9.     remote:
  10.     remote: ---- Building application image ----
  11.     remote:  ---> Sending image to repository (5.57MB)
  12.     remote:  ---> Cleaning up
  13.     remote:
  14.     remote:  ---> Started unit b21298a64e...
  15.     remote:
  16.     remote: ---- Binding and checking 1 new units ----
  18.     remote:
  19.     remote: ---- Adding routes to 1 new units ----
  20.     remote:  ---> Added route to unit b21298a64e
  21.     remote:
  22.     remote: OK
  23.     To git@192.168.50.4.nip.io:helloworld.git
  24.      * [new branch]      master -> master

如果遇到"Permission denied (publickey)."的错误，请确保你是团队一员并把公钥加到tsuru中。用key-add命令添加公钥：

使用git remote add命令来避免每次push代码时都要输入整个远程仓库的链接：

  1.     $ git remote add tsuru git@192.168.50.4.nip.io:helloworld.git

然后运行：

  1.     $ git push tsuru master
  2.     Everything up-to-date

运行应用

tsuru会自动编译和运行应用，但是也可以定制tsuru编译和运行应用的方式。更多内容，请查看Go平台的README：.

应用部署成功，可以通过app-list命令获得IP或者主机名，然后用浏览器去访问。比如，在下面的列表中：

  2.     $ tsuru app-list
  3.     +-------------+-------------------------+--------------------------------+
  4.     | Application | Units State Summary     | Address                        |
  5.     +-------------+-------------------------+--------------------------------+
  6.     | helloworld  | 1 of 1 units in-service | helloworld.192.168.50.4.nip.io |
  7.     +-------------+-------------------------+--------------------------------+

顺利完成！现在我们有了一个部署在tsuru上的简单go项目，现在我们可以访问app-list返回的blog app的URL了。(本例中的URL是"helloworld.192.168.50.4.nip.io").
