docker discovery usefull commands




Some usefull commands and settings when using docker

# docker login
Will create a .dockercfg file which is reusable on other hosts
Usefull if you choosed a PITA username and password, like I did.
# docker pull xxx
# docker --name zzz run xxx:yyy
Can be chortened as
# docker run --name zzz [...] xxx:yyy
It will pull for you.
If the container zzz ever stopped
# docker start zzz
Show the full parameters of a container
# docker inspect zzz
You'll see it's a JSON file, and if you just want to print some parameters:
# docker inspect --format '{{.NetworkSettings.IPAddress}}' zzz

This did the job! The command to issue is then: npm run build -- --base-href='https://ngx.rktmb.org/foo...

wget maven ntlm proxy

How to make wget, curl and Maven download behind an NTLM Proxy Working on CentOS, behind an NTLM proxy: yum can deal without problem with a NTLM Proxy wget, curl and Maven cannot The solution is to use " cntlm ". " cntlm " is a NTLM client for proxies requiring NTLM authentication. How it works Install "cntlm" Configure "cntlm"  by giving it your credentials by giving it the NTLM Proxy Start "cntlm" deamon (it listens to "127.0.0.1:3128") Configure wget, curl and Maven to use "cntlm" instead of using directly the NTLM Proxy Note: You will have then a kind of 2 stages Proxy : cntlm + the NTLM proxy Configure CNTLM After installing cntlm, the configuration file is in "cntlm.conf". You must have your domain (in the Windows meaning), proxy login and  proxy password. Mine are respectively: rktmb.org, mihamina, 1234abcd (yes, just for the example) You must have you NTLM Proxy Hostnama or IP ...
