How to use curl command to get value of consul key from https end point from jenkins bash script

[RSriv]

I am using Jenkin job to automatically update the consul key using https endpoint. The syntax I am using to update the consul key using curl command in bash script is below which works fine:-

curl -f -s --show-error "https://example.com/a/b/c?AdminKey=xxxxx&token=yyyyyyy&value=nnn”. (Here key is -->a/b/c)

The above command updates value of consul key "a/b/c" with “nnn”

Now I want to fetch the value of same key in a variable then how I can fetch it using Jenkins job (bash script and curl command)  similar to what I have mentioned above?

Note: I have tried curl command such as variable=`curl -f -s --show-error "https://example.com/a/b/c?AdminKey=xxxxx&token=yyyyyyy”` but it is not working.

Thanks

Hello,

I saw you posted this question on both the Discuss forums [1] and StackOverflow [2]. I provided answers there, but wanted to close the loop on this thread as well in case you did not see those replies.

You can update a key using this syntax.

curl --request PUT --fail --silent --show-error "http://localhost:8500/v1/kv/a/b/c?token=<token>" --data 'nnn'

The value can then be retrieved and stored in a variable using this command.

export VARIABLE=$(curl --fail --silent --show-error "http://localhost:8500/v1/kv/a/b/c?token=<token>&raw")

See https://www.consul.io/api-docs/kv for more info on the supported arguments for these API calls.

Best,
