Im trying to redirect to docker containers using nginx but when accessing my server from an ‘external pc'(host and other vagrant machines) the address doesn’t resolve. I have passed ‘host.docker.internal:172.17.0.1’ to the containers host file but still no success. Im testing this using vagrant. The server is running Ubuntu Server 21.10 and curling the address from here works.
default nginx conf:
server {
listen 80;
listen [::]:80;
server_name localhost;
#access_log /var/log/nginx/host.access.log main;
location /dockercontainer_1 {
return 301 http://host.docker.internal:79;
}
location /dockercontainer_2 {
return 301 http://host.docker.internal:34;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}
nginx container host file:
127.0.0.1 localhost
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.17.0.1 host.docker.internal
172.17.0.4 35fced58d2eb
Ubuntu Server hosts file:
127.0.0.1 localhost
127.0.1.1 vagrant
127.0.0.1 host.docker.internal
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

to access containers from external machine you need to tell nginx to serve on your public
ip
address so just edit the forth line of default nginx config file :this line:
To this:
change
127.0.0.1
to the public ip address of your machine.Lets say that you initiate 2 nginx container with the following command
Then you should edit your localtion block in the host machine
