安装superset官方容器

1.主机上安装好docker

2.主机上安装好dnscrypt-proxy（用于解决dns污染），参考Installation linux · DNSCrypt/dnscrypt-proxy Wiki · GitHub

3.主机上装好http代理服务用于容器访问github示例数据

Docker Hubhttps://hub.docker.com/r/apache/superset安装并启动容器后，先不要运行初始化，需要作一些修改：

安装vim、修改dns：

# 以root身份进入容器安装好vim
docker exec -it -u root superset /bin/bash
apt update
apt install vim
# 还可以设置一下root密码
passwd

# 按dnscrypt-proxy文档修改dns，其中的ip换为主机的
vim /etc/resolv.conf

修改代理、代码：

# 进入容器
docker exec -it superset /bin/bash
# 设置代理，ip和端口指向主机代理服务，替换为自己的
export http_proxy=http://172.17.0.1:1081
export https_proxy=http://172.17.0.1:1081

# 具体修改内容见后面
vim /app/superset/examples/helpers.py

# 具体修改内容见后面
vim /app/superset/datasets/commands/importers/v1/utils.py

修改容器内/app/superset/examples/helpers.py

# 头部引入requests
import requests

# 注释以下3行
#content = request.urlopen(  # pylint: disable=consider-using-with
#    f"{base_URL}{filepath}?raw=true"
#).read()

# 紧随其后增加以下4行
res = requests.get(
    f"{base_URL}{filepath}?raw=true"
)
content = res.content

 修改容器内/app/superset/datasets/commands/importers/v1/utils.py

# 修改load_data方法
# 注释此行
#data = request.urlopen(data_uri)  # pylint: disable=consider-using-with
# 随后增加以下两行
res = requests.get(data_uri)
data = io.BytesIO(res.content)

将urllib修改为requests的目的是解决以下错误：
http.client.RemoteDisconnected: Remote end closed connection without response

找到config.py，修改BABEL_DEFAULT_LOCALE为zh，注释LANGUAGES = {}，重启容器：

docker restart superset

# ---------------------------------------------------
# Babel config for translations

# Setup default language
BABEL_DEFAULT_LOCALE = "zh"
# Your application default translation path
BABEL_DEFAULT_FOLDER = "superset/translations"
# The allowed translation for you app
LANGUAGES = {

# Turning off i18n by default as translation in most languages are
# incomplete and not well maintained.
# LANGUAGES = {}
