OSError: protocol not found

you should have a /etc/protocols file. It must have been deleted somehow. It comes from the netbase package.

apt install -y netbase

安装git, 并确保该目录下有.git文件夹

pip安装报SSLError: The read operation timed out的问题

增加--default-timeout=100，加大超时时间

$ pip install -r requirements.txt

......
ReadTimeoutError: HTTPSConnectionPool(host='pypi.python.org', port=443): Read timed out.

解决办法：

$ pip --default-timeout=100 install -r requirements.txt

$ docker run -dti ...
docker: Error response from daemon: service endpoint with name XXX already exists.

解决办法：

$ docker network ls

CRITICAL keystonemiddleware.auth_token  Unable to validate token: Identity server rejected authorization necessary to fetch token data

解决办法：

1）确认XXX.conf中的keystone_authtoken配置是否正确，主要检查用户名、密码、工程名等。

2）问题依旧未解决，必须查看keystone的日志进一步确认。

我在排查问题时犯了一个严重的错误，想当然的认为配置就是对的，忙糊涂啦。

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

解决办法：

for scrapy with Python 3, you'll need

sudo apt-get install python3 python-dev python3-dev 
     build-essential libssl-dev libffi-dev 
     libxml2-dev libxslt1-dev zlib1g-dev 
     python-pip

with Python 2, you'll need

sudo apt-get install python-dev  
     build-essential libssl-dev libffi-dev 
     libxml2-dev libxslt1-dev zlib1g-dev 
     python-pip

$ curl 127.0.0.1:9200
curl: (52) Empty reply from server

解决办法：

docker container 的/etc/hosts不能配置127.0.0.1 或者192.168.0.1

否则宿主机器将无法访问端口
