Condition
Host could not visit Intenet directly, need to set up proxy to connect Internet. Under this situation, the docker containers could not visit Internet directly either.
Solution
Option 1
Change the route table, transfer all request to host (this was succeed, but I could not recall the details, need verified later)
Option 2
In docker instance, using below command to change the network:
export http_proxy=
export https_proxy=
export no_proxy=
In addition, if you meet DNS problem, manually update
/etc/resolv.conf
could work for one time (invalid after
reboot or reconnect, for persist this conf please google).
You could also add above configuration in
docker-compose.yml
if you are running instance by this
file.
version: '3'
services:
web:
build: .
ports:
- "5000:5000"
volumes:
- .:/code
environment:
FLASK_ENV: development]
http_proxy: xxxx # update here
redis:
image: "redis:alpine"
DNS error, could not resolve xxx….
If the DNS you are setting is a domain name, try to use IP address directly.
