I am trying to run some jq command over ssh-agent in a Jenkins pipeline. But I am getting the following error: Trying to run: `

        stage("common-infra-deployment"){
            steps{
                sshagent (credentials: ['test-private-key']){
                    script{
                       
                        sh '''
                        sudo ssh -o StrictHostKeyChecking=no [email protected] "
                        jq '.outputs | {"kubeconfig-file"}' terraform.tfstate;
                        "
                        '''

                    }
                }
            } 
        }

`

Error: `

jq: error: syntax error, unexpected '-', expecting '}' (Unix shell quoting issues?) at <top-level>, line 1:

terraform.tfstate `

I tried \ to escape '-' and '{}' but nothings working out. I want the jq to be executed over ssh session.

CodePudding user response：

You must escape your double quotes inside your double quotes:

sudo ssh -o StrictHostKeyChecking=no [email protected] "
jq '.outputs | {\"kubeconfig-file\"}' terraform.tfstate;
"

Perhaps the backslash needs to be escaped itself:

sudo ssh -o StrictHostKeyChecking=no [email protected] "
jq '.outputs | {\\"kubeconfig-file\\"}' terraform.tfstate;
"
