Not able to add host using docker-machine -

-

i have docker-engine installed on linux vm on company data center. installed docker-machine on windows. want manage docker-engine through windows machine. want add host , executed following command:

docker-machine create -d generic --generic-ip-address 10.51.227.5 --generic-ssh-port 22 --generic-ssh-user root compute

but getting following error after waiting couple of minutes

running pre-create checks... creating machine... (compute) no ssh key specified. connecting machine , in future require ssh agent contain appropriate key. waiting machine running, may take few minutes... detecting operating system of created instance... waiting ssh available... error creating machine: error detecting os: many retries waiting ssh available.  last error: maximum number of retries (60) exceeded

i don't know doing wrong.

try using native ssh

unfortunately, can happen multiple reasons, since you're running on windows, have guess. try using native ssh client - is, go library ships docker, rather ssh.exe. so, pass --native-ssh argument docker-machine:

docker-machine --native-ssh create --driver generic --generic-ip-address example.com examplemachine

examining debug output

you can examine various debugging messages passing --debug argument. when did that, , did not specify --native-ssh argument, got lots of error messages:

> docker-machine create --driver generic --generic-ip-address example.com examplemachine <...snip...> waiting ssh available... getting waitforssh function... (apsylania) calling .getsshhostname (apsylania) calling .getsshport (apsylania) calling .getsshkeypath (apsylania) calling .getsshkeypath (apsylania) calling .getsshusername using ssh client type: external &{[-f /dev/null -o passwordauthentication=no -o stricthostkeychecking=no -o userknownhostsfile=/dev/null -o loglevel=quiet -o connectionattempts=3 -o connecttimeout=10 -o controlmaster=no -o controlpath=none root@example.com -o identitiesonly=yes -i c:\users\myaccount\.docker\machine\machines\examplemachine\id_rsa -p 22] c:\program files\openssh-win64\ssh.exe <nil>} run ssh command: exit 0 ssh cmd err, output: exit status 255: error getting ssh command 'exit 0' : ssh command error: command : exit 0 err     : exit status 255 output  : getting waitforssh function... <...snip...>

my guess, after trying pass --generic-ssh-key backslashes on windows , having produce error, docker (still) isn't quite polished on windows be, , wondered if there buggy way calls out external ssh client. since using native go ssh client worked me, think guess correct, @ least case.

Sass watch command compiles .scss files before full sftp upload -

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
