龙芯Fedora21平台portainer部署方案

http://ask.loongnix.org/?/article/90

一、下载portainer官方镜像
1.在loongnix上下载镜像

[root@loongson ~]# docker pull docker.io/portainer/portainer:1.14.3
Using default tag: 1.14.3
Trying to pull repository docker.io/portainer/portainer ... 
unauthorized: authentication required

2.根据控制台反馈结果unauthorized: authentication required，提示无权限，因为该镜像不支持 mips64el,所以无法下载镜像到本地，可使用X86机器进行下载该镜像

[root@X86 ~]# docker pull docker.io/portainer/portainer:1.14.3

3.提示下载成功，查看本地镜像

[root@X86 ~]# docker images
REPOSITORY                       TAG   IMAGE ID  
docker.io/portainer/portainer   1.14.3 457fb8fa57b0

4.确认本地镜像docker.io/portainer/portainer已存在,运行该镜像

[root@X86 ~]# docker run -i -t docker.io/portainer/portainer:1.14.3

5.使用Docker export命令导出当前镜像创建的容器为tar包

[root@X86 ~]# docker export 36ceef361070 > loongson-portainer.tar

6.将loongson-portainer.tar包拷贝到loongson机器上，这里使用scp命令进行拷贝

[root@X86 ~]# scp loongson-portainer.tar [email protected]:/root/portainer/

7.在loongnix机器上解压loongson-portainer.tar

[root@loongson portainer]# tar xf loongson-portainer.tar

8.经分析，需要重新编译的二进制文件为portainer

[root@loongson portainer]# file portainer 
portainer: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, stripped

接下来，从github下载portainer源代码，重新编译portainer
二、从github下载portainer源代码
1.设置GO语言参数—GOPATH

export GOPATH=/usr/share/gocode

2.使用go get 从github中下载源代码

[root@loongson portainer]# go get github.com/portainer/portainer

package github.com/portainer/portainer: no buildable Go source files in /usr/share/gocode/src/github.com/portainer/portainer

这里出现了错误提示，但是没有关系，go get 命令相当于先下载，再安装两个步骤，上面的提示是安装失败，我们需要的是源代码，因此可以忽略此提示
3.打开源代码所在文件夹

[root@loongson portainer]# cd $GOPATH/src/github.com/portainer/portainer

4.因为只需要编译源代码中的api部分所以将此文件夹下的其他内容全部删除

[root@loongson portainer]# rm -rf app assets bower.json build build.sh codefresh.yml CODE_OF_CONDUCT.md CONTRIBUTING.md gruntfile.js index.html LICENSE package.json README.md test vendor.yml distribution

5.因为go语言文件中的的目录的相对路径和源代码中的相对路径不同，所以需要对源代码的相对路径做调整

[root@loongson portainer]# cp -rf api/* $GOPATH/src/github.com/portainer/portainer

6.删除源代码中的api文件夹

[root@loongson portainer]# rm -rf api/

三、编译portainer源代码
1.打开main.go所在目录

[root@loongson portainer]# cd $GOPATH/src/github.com/portainer/portainer/cmd/portainer

2.执行go build 命令，开始进行代码编译

[root@loongson portainer]# go build main.go 
../../../../../gopkg.in/alecthomas/kingpin.v2/usage.go:10:2: cannot find package "github.com/alecthomas/template" in any of:
	/usr/lib/golang/src/github.com/alecthomas/template (from $GOROOT)

3.根据提示需要加载github.com/alecthomas/template

[root@loongson portainer]# go get github.com/alecthomas/template

4.再次执行go build 命令，开始进行代码编译

[root@loongson portainer]# go build main.go

	/usr/share/gocode/src/github.com/boltdb/bolt (from $GOPATH)

9.根据提示需要加载github.com/boltdb/bolt

[root@loongson  portainer]# go get github.com/boltdb/bolt
# github.com/boltdb/bolt
../../../../boltdb/bolt/db.go:101: undefined: maxMapSize
../../../../boltdb/bolt/db.go:101: invalid array bound maxMapSize

10.根据提示缺少变量maxMapSize,那么接下来创建变量，首先打开boltdb所在目录

[root@loongson  portainer]# cd $GOPATH/src/github.com/boltdb/bolt

11.创建适用于mips64el平台的bolt

[root@loongson  bolt]# cp bolt_amd64.go bolt_mips64el.go

12.打开main.go所在目录

[root@loongson bolt]# cd $GOPATH/src/github.com/portainer/portainer/cmd/portainer/

13.再次执行go build 编译文件

[root@loongson portainer]# go build main.go 
../../jwt/jwt.go:9:2: cannot find package "github.com/dgrijalva/jwt-go" in any of:
	/usr/lib/golang/src/github.com/dgrijalva/jwt-go (from $GOROOT)
	/usr/share/gocode/src/github.com/dgrijalva/jwt-go (from $GOPATH)

14.根据提示需要加载github.com/dgrijalva/jwt-go

[root@loongson portainer]# go get github.com/dgrijalva/jwt-go

16.根据提示需要加载github.com/gorilla/mux

[root@loongson portainer]# go get github.com/gorilla/mux

17.再次执行go build 命令，开始进行代码编译

[root@loongson portainer]# go build main.go 
../../jwt/jwt.go:10:2: cannot find package "github.com/gorilla/securecookie" in any of:
	/usr/lib/golang/src/github.com/gorilla/securecookie (from $GOROOT)
	/usr/share/gocode/src/github.com/gorilla/securecookie (from $GOPATH)

18.根据提示需要加载github.com/gorilla/securecookie

[root@loongson portainer]# go get github.com/gorilla/securecookie

19.再次执行go build 命令，开始进行代码编译

[root@loongson portainer]# go get github.com/robfig/cron

23.再次执行go build 命令，开始进行代码编译

[root@loongson portainer]# go build main.go 
../../crypto/crypto.go:4:2: cannot find package "golang.org/x/crypto/bcrypt" in any of:
	/usr/lib/golang/src/golang.org/x/crypto/bcrypt (from $GOROOT)
	/usr/share/gocode/src/golang.org/x/crypto/bcrypt (from $GOPATH)
../../http/handler/websocket.go:21:2: cannot find package "golang.org/x/net/websocket" in any of:
	/usr/lib/golang/src/golang.org/x/net/websocket (from $GOROOT)
	/usr/share/gocode/src/golang.org/x/net/websocket (from $GOPATH)

24.根据提示需要加载golang.org/x/crypto/bcrypt和golang.org/x/net/websocket
注意：$GOPATH的路径已经不再是/usr/share/gocode/src/github.com/...
而是/usr/share/gocode/src/golang.org/x/...
所以需要先创建文件夹

[root@loongson portainer]# mkdir -p $GOPATH/src/golang.org/x/

25.切换至该文件夹下

[root@loongson portainer]# cd $GOPATH/src/golang.org/x/

26.加载golang.org/x/crypto/bcrypt

[root@loongson x]# git clone https://github.com/golang/crypto.git

27.加载golang.org/x/net/websocket

[root@loongson x]# git clone https://github.com/golang/net.git

28.切换至main.go所在目录

[root@loongson x]# cd $GOPATH/src/github.com/portainer/portainer/cmd/portainer/

29.再次执行go build 命令，开始进行代码编译

[root@loongson portainer]# go build main.go

30.编译完成，当前目录生成文件名为main的二进制可执行文件，下面需要拷贝到loongson-portainer.tar 解压目录，替换掉二进制文件portainer

四、loongson-portainer.tar二进制文件替换
1.修改编译完成后二进制文件的文件名

[root@loongson portainer]# mv main portainer

2.拷贝loongson-portainer.tar 解压目录，替换掉二进制文件portainer

[root@loongson portainer]# cp -f portainer /root/portainer/

3.切换至loongson-portainer.tar 解压目录

[root@loongson portainer]# cd /root/portainer/

4.运行二进制文件portainer

[root@loongson portainer]# ./portainer

5.打开浏览器,输入网址http://localhost:9000

6.切换至loongson-portainer.tar 解压目录的上级目录

[root@loongson portainer]# cd /root/

7.压缩整个portainer文件夹

[root@loongson ~]# tar -cvf portainer.tar portainer/

五、制作portainer镜像
1.在loongnix上下载fedora21-tools基础镜像

[root@loongson ~]# docker pull docker.io/huangxg20171010/feodra21-tools
REPOSITORY                                     TAG  
docker.io/huangxg20171010/fedora21-tools       latest

2.运行feodra21-tools基础镜像

[root@loongson ~]# docker run -i -t docker.io/huangxg20171010/fedora21-tools

3.基础镜像运行成功后，会自动进入镜像控制台，由[root@loongson ~]变成[root@1cb98e167e49 /],说明容器创建成功，下面切换目录至root下

[root@1cb98e167e49 /]# cd /root/

4.将第四节第7步压缩的portainer.tar拷贝到当前容器的root目录下

[root@1cb98e167e49 ~]# scp [email protected]:/root/portainer.tar /root/

5.将portainer.tar解压到当前目录

[root@1cb98e167e49 ~]# tar xvf portainer.tar

6.删除压缩文件portainer.tar

[root@1cb98e167e49 ~]# rm -f portainer.tar

7.切换至portainer目录下

[root@1cb98e167e49 ~]# cd /root/portainer

8.创建执行文件run-portainer.sh

[root@1cb98e167e49 ~]# vi /root/portainer/run-portainer.sh

9.run-portainer.sh文件内容如下

#!/bin/bash
export LC_ALL=zh_CN.UTF-8
export LANG=zh_CN.UTF-8
cd /root/portainer
./portainer

10.修改run-portainer.sh文件权限

[root@1cb98e167e49 ~]#chmod +x /root/portainer/run-portainer.sh

11.创建portainer所需文件夹

[root@1cb98e167e49 ~]#mkdir -p /data/tls

12.退出当前容器

[root@1cb98e167e49 ~]# exit

13.展示所有已创建容器

[root@loongson /]# docker ps -a
CONTAINER       IMAGE                 
1cb....         docker.io/huangxg20171010/fedora21-tools

14.使用Docker commit生成一个新镜像

[root@loongson /]# docker commit --change='CMD ["/root/portainer/run-portainer.sh"]' 1cb98e167e49 portainer

15.查看制作的新镜像

[root@loongson /]# docker images
REPOSITORY   TAG     IMAGE ID         CREATED   
portainer   latest  085a675a35d7   12 seconds ago

六、上传portainer镜像
1.申请docker hub 帐号
打开 docker hub官网：https://hub.docker.com 进行注册

2.邮件激活后登录docker hub 点击 Create --> Create repository 创建一个仓库

3.本机登录Docker hub帐号

[root@loongson /]# docker login
Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one.
Username: jiangxinshang
Password: 
Login Succeeded

4.将本机已经存在的镜像名称做格式化，保证和仓库名称：jiangxinshang/portainer 一致，操作如下：

[root@loongson /]# docker tag portainer:latest jiangxinshang/portainer

5.使用 docker push 将镜像上传至hub上，操作如下：

[root@loongson /]# docker push jiangxinshang/portainer
The push refers to a repository [docker.io/jiangxinshang/portainer]
572868387250: Pushed

6.查看所上传镜像

[root@loongson /]# docker search jiangxinshang/portainer

七、下载并运行portainer镜像
1.下载portainer镜像

[root@loongson /]# docker pull jiangxinshang/portainer

2.查看已下载镜像

[root@loongson /]# docker images
 REPOSITORY                           TAG   
docker.io/jiangxinshang/portainer   latest

3.运行该镜像

[root@loongson /]# docker run -i -t --name portainer -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock docker.io/jiangxinshang/portainer

4.打开浏览器，输入网址http://localhost:9000

==================================================================================
X86版本的portainer官方镜像docker.io/portainer/portainer 已更新版本，可通过docker pull portainer/portainer:1.14.3来获取镜像，portainer的github源代码请下载版本v1.14.3
