docker-compose 安装以及遇到的错误解决

今天在编译一个docker项目到时候，遇到了很多问题。记录一下

架构：Python+Django+bootstrap+SaltStack+Zabbix+MySQL

1 bash: docker-compose: command not found...

[root@localhost mysite]# docker-compose build
bash: docker-compose: command not found...
[root@localhost mysite]# pip -V

[root@localhost opt]# pip install docker-compose
ERROR: jsonschema 3.2.0 has requirement six>=1.11.0, but you'll have six 1.9.0 which is incompatible.
[root@localhost mysite]# pip install six --user -U
ImportError: No module named configparser

很多关于configparser，说是python 3.x修改了名字

[root@localhost mysite]# pip uninstall docker-compose
[root@localhost mysite]# pip install docker-compose
[root@localhost mysite]# docker-compose --version
[root@localhost mysite]# find / -name docker-compose

1.15.0
[root@localhost mysite]# python -c 'import six.moves; print(dir(six.moves))'
--pip install --user pytz requests tqdm tzlocal python-dateutil
--pip install configparser

还是不行，于是把python2换成python3.6试试

安装docker-compose

方法1（在线安装，网络问题）
# yum -y install libcurl libcurl-devel
# curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose
# chmod +x /usr/local/bin/docker-compose
# docker-compose --version

方法2 
安装python-pip
yum -y install epel-release
yum -y install python-pip
安装docker-compose
pip install docker-compose
pip install -U docker-compose==1.23.2

方法3 离线安装
https://github.com/docker/compose/releases/tag/1.23.2
下载安装包docker-compose-Linux-x86_64
[root@localhost opt]# mv docker-compose-Linux-x86_64  /usr/local/bin/docker-compose
mv: overwrite ‘/usr/local/bin/docker-compose’? y
[root@localhost opt]# chmod +x /usr/local/bin/docker-compose
[root@localhost opt]# docker-compose --version
Traceback (most recent call last):
  File "/usr/bin/docker-compose", line 5, in <module>
    from compose.cli.main import main
ModuleNotFoundError: No module named 'compose'

问题依旧：

以使用国内的pip源进行加速
[root@localhost opt]# pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple -U docker-compose
[root@localhost opt]# docker-compose --version
docker-compose version 1.26.2, build unknown

[root@localhost mysite]# docker-compose build
pip._vendor.requests.packages.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host='pypi.tuna.tsinghua.edu.cn', port=443): Read timed out.
You are using pip version 9.0.1, however version 20.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
ERROR: Service 'web' failed to build: The command '/bin/sh -c pip install -i https://pypi.tuna.tsinghua.edu.cn/simple -r requirements.txt' returned a non-zero code: 2
修改文件/mysite/Dockerfile
把pip修改为pip3
pip._vendor.requests.packages.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host='pypi.tuna.tsinghua.edu.cn', port=443): Read timed out.
ERROR: Service 'web' failed to build: The command '/bin/sh -c pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple -r requirements.txt' returned a non-zero code: 2
[root@localhost mysite]# pip3 --default-timeout=100 install -U pip
[root@localhost mysite]# docker-compose build ##执行成功
[root@localhost mysite]# docker images
