How to User SCP command to copy Files from one server to another server using CA RA Tool

[Legacy User]

Hi I need a help to use the SCP command  or Copy filese from one server to another server on linux/unix environment by using CA Release Automation Tool.

 

Please any one is having sample docs or information post me.

Hello,

 

If you are required to use the scp command then you can try passing the exact command that you want through the "Run Command Line" action and then parameterize it to your liking. But there are other actions like "Put File (SSH)", "Get File (SSH)", "Get File Or Folder From Remote Agent", "Put File Or Folder in Remote Agent", etc.. that you can possibly use to achieve the same thing.

Hi Gregg,

 

I am trying to use run command line action but getting below error message,

 

Description:

Run Command Line action has finished successfully. Return value: 1 Std out: Std err: Host key verification failed.  Command line executed: /bin/sh -c scp [e-mail]:/opt/app/add-on/production_staging/R116/production_0416/PricerD/Pricing.war /opt/app/capio/release/PricerD_wbl_release/deploy_20160613

Hi Gregg,

 

Also when use SSH actions that time i am getting below error message,

 

Description:

No password and no keystore file is given - unable to proceed with authentication

 

I am not aware what is Keystore files. also I instaaled the agent with user as Capio. as mentioned in earlier scp command.

Hello,

 

I think the key for getting this to work will be to:

a. Understand that when executed via Release Auto you will not be able to provide a password to the password prompt. It must be completely unattended.

b. Get it to work (under the guidelines of #1) manually on the agent machine using the login ID that owns the nolioagent process (or another user - but that will require other RA settings like setting up the action and agent process owner to use sudo)

 

based on this stackoverflow q&a it looks like you cannot pass the users password via an scp argument. And now I remember a similar situation that I tried to accommodate by using an expect script. The alternative to an expect script is to use ssh keys for the scp command. If you want to use this option the have a look at the section named

SSH and SCP Without Passwords"

Hi Gregg,

 

Thanks for your response and help. it helped me a lot. Now I able to connect my source server to get a file on the target server by using Get File (SSH) action, but this action is not able to copy a single file from source (/opt/app/add-on/production_staging/R116/abc.war) to target if I specify the name of file in a path. and if i remove the file name (/opt/app/add-on/production_staging/R116/) it works and copy all files from source to target.

My requirement is to copy a single file from source to target.

 

any idea how this Get file (ssh) action works internally.

[Gregg Stewart]

Ahh, glad to hear you are making progress. Regarding the situation you're in now, what do you use in the "Full Target File Path" field when the "Full Source File Path" field is pointing to a file? I believe the "Full Target File Path" field should also point to a final filename.

 

Example:

Full Source File Path: /opt/app/add-on/production_staging/R116/abc.war

Full Target File Path: /opt/app/add-on/production_staging/R116/abc.war

or maybe

Full Target File Path: /opt/app/add-on/production_staging/R116/somethingDifferent.war

 

Cheers,
Gregg

Hi Gregg,

 

If I mention full source path (with filename) as /opt/app/add-on/production_staging/R116/abc.war, the action gets failed and if i mentioned full source path as "/opt/app/add-on/production_staging/R116/" i.e. without file name its successful and copy all files from source to target.

Here are the action test logs for your reference,

 

Failes Scenario:

Description:

Failed to retrieve file from [zltv3227.vci.att.com: /opt/app/add-on/production_staging/R116/production_0416/PricerD/Pricing.war] to [local: /opt/app/capio/release/PricerD_wbl_release/deploy_20160613], Target is existing directory (/opt/app/capio/release/PricerD_wbl_release/deploy_20160613) but source is not a directory (/opt/app/add-on/production_staging/R116/production_0416/PricerD/Pricing.war)

 

Success Scenario:

Agent:	cappoc.snt.bst.bls.com
Description:	Successfully retrieved file from [zltv3227.vci.att.com: /opt/app/add-on/production_staging/R116/production_0416/PricerD/] to [local: /opt/app/capio/release/PricerD_wbl_release/deploy_20160613].

[Gregg Stewart]

It looks like it fails because you're still not providing a filename in the full target field. It looks like you're just giving a directory name and so its effectively trying to replace a folder with a filE which can't be done.

Hi Gregg,

 

In this path /opt/app/add-on/production_staging/R116/production_0416/PricerD/Pricing.war

 

Pricing.war is my file name on source server and its mentioned in a full source path and it fails when I mention filename in a source path.

[Gregg Stewart]

Right. What I'm saying is that you should include Pricing.war at the end of your target path. Right now it looks like it only has a directory. It needs a filename at the end.

Thank you so much Gregg. This worked perfectly. I was thinking in a normal way as a=like copy action for target path.

 

KB here is : To use Get File(ssh) action we should specify the file names to be copied in both source and target path.

[Gregg Stewart]

Great. Good idea for a KB, thanks! I'll work on getting that prepared tomorrow.

 

Cheers,
