Copy files between nodes with ansible -

-

i found this post copying files between nodes ansible. here's ansible task:

- name: copy pipeline files   synchronize: mode=pull src=/home/ec2-user/nlp/nlp_test/all_data/test/ dest=/opt/nlp-ml/rate/pipeline dirs=yes   delegate_to: "{{ ml_ip }}"

i tried out playbook failed message:

msg: warning: identity file /users/me/me.pem not accessible: no such file or directory. permission denied (publickey).

this makes sense identity file stored locally , not on remote machine. however, source node's public key has been distributed target node. how can around this?

edit: tried adding destination node's public key source node. added use_ssh_args=yes synchronize task. after added ssh_args = -i /home/ec2-user/.ssh/id_rsa (the location of private key on both source , destination nodes) ansible.cfg. same issue.

so in order requires combination of things tried. @vvchik suggested try removing mode=pull, didn't work initially. however, when combined use_ssh_args, able working. full solution, here is:

generate ssh key on source node (in default location , without password) , install on destination nodes. add task:

- name: copy files source destination   synchronize: src=source dest=destination dirs=yes use_ssh_args=yes   delegate_to: "{{ source_ip }}"

finally, in ansible.cfg add ssh_args = -i /home/user/.ssh/id_rsa. ansible.cfg should in current directory.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
