docker - Site can't be reached -


i using jwilder/nginx-proxy:alpine image create container.here link nginx-proxy.

docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock.ro --name nginx \ jwilder/nginx-proxy:alpine

i have created container running up. then, start container proxied environment variable 

  docker run \     -d \     --entrypoint /docker-entrypoint.sh \     -e virtual_host=xyz.mydomain.info \ //running app on xyz.mydomain.info,but      not working.     -e virtual_port=8000 //what mean?     --name server \     image_name

the container named server , running.

question1: need open port in ec2 security groups in order run application?

question2: can see application running on xyz.mydomain.info.

question3: use of virtual_port here? in dockerfile container's expose on port 8000.

question1: need open port in ec2 security groups in order run application?

only 80 or 443, depending on 1 using. rest work internally on machine

question2: can see application running on xyz.mydomain.info

by either pointing dns entry of domain server, or creating host entry in os hosts file (for testing purpose)

question3: use of virtual_port here? in dockerfile container's expose on port 8000.

nginx-proxy needs understand port should proxy passing traffic inside container. default takes exposed port. if there multiple can specify 1 using virtual_port

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
