I am trying to use jq in the following to get a status on my pod "my pod":
curl '127.0.0.1:8080/api/v1/pods' | jq -r '.items[] | select(.metadata.name)'
This give me a ton of json, more specific how do you read json from k8s api - to get the status of a pod - running or not?
If I get items within a pod:
curl '127.0.0.1:8080/api/v1/pods' | jq -r 'select(.items[].metadata.name="go-test-volume1").items[]
Sure enough I get a list, but which one to chose - there is a status.phase in all of them?
In the case of a status of CrashLoopBackOff:
curl '127.0.0.1:8080/api/v1/pods' |
jq -r '.items[] | select(.metadata.name == "my-pod").status.phase'
Will show it as Running?
This is what you need :
curl '127.0.0.1:8080/api/v1/pods' |
jq -r '.items[] | select(.metadata.name == "my-pod").status.phase'
This will give you the right status:
curl '127.0.0.1:8080/api/v1/pods' |
jq -r '.items[] | select(.metadata.name == "my-pod).status.containerStatuses[0].state'
curl -k -s -X POST "https://phabricator_URL.eu/api/project.edit" \
-d api.token=api-myapitoken \
-d members.add=TestMember \
-d name=TestProject \
-d objectIdentifier= | jq -r
ERROR receive:
{
"result": null,
"error_code": "ERR-CONDUIT-CALL",
"error_info": "API Method \"project.edit\" does not define these parameters: 'members.add', 'name'."
}
Link Used:
https://secure.phabricator.com/conduit/method/project.edit/
You have to specify members.add as part of a list of transactions, and the users to add must also be a list:
curl -k -s -X POST "https://phabricator_URL.eu/api/project.edit" \
-d api.token=api-myapitoken \
-d transactions[0][type]=name
-d transactions[0][value]=TestProject \
-d transactions[1][type]=members.add \
-d transactions[1][value][0]=PHID-USER-5555 \
-d objectIdentifier= | jq -r
If you submit the API call you want to make through the conduit doc page, it will display the curl call needed to perform those same actions.
I'm trying to parse the output of AWS cli using jq where the jq query contains bash variables and by using the --arg switch like so:
$ aws ec2 describe-instances --region $region | jq --arg environment "$Environment" --arg br "$BUILD_NUMBER" --arg app "$App" -r '.Reservations[].Instances[].Tags[]?.Value | select(startswith("Company-$environment-$br-$app")
I get a new line when I run the command.
This is the output when I use hard coded auto scaling group name:
itai#Itais-MBP ~/Downloads - $ aws ec2 describe-instances --region $region | jq --arg environment "$Environment" --arg br "$BUILD_NUMBER" --arg app "$App" -r '.Reservations[].Instances[].Tags[]?.Value | select(startswith("Company-Dev-60-Api") )'
Company-Dev-60-ApiServersASG-19L10K16RUXTE
Company-Dev-60-ApiServersASG-19L10K16RUXTE
itai#Itais-MBP ~/Downloads - $
You can see the values of the variables are set:
itai#Itais-MBP ~/Downloads - $ echo $Environment
Dev
itai#Itais-MBP ~/Downloads - $ echo $App
Api
itai#Itais-MBP ~/Downloads - $ echo $BUILD_NUMBER
60
So what am I doing wrong?
The jq language has its own way of combining variables. In jq, the expression you wrote:
"Company-$environment-$br-$app"
is just a vanilla JSON string.
One option would be to use jq's support for interpolation:
"Company-\($environment)-\($br)-\($app)"
Another option would be to use jq's string-concatenation operator, +.
You could also use join("-"). And so on.
I had downloaded jq and trying to get a hang of it on Windows.
I am able to run some basic queries in jq but when I am trying to use select with jq I am getting the below mentioned message.
Below is the command which I am executing.
curl --basic -u admin:admin http://XX.XX.XX.XX:8080/mmc-console-3.7.3/api/deployments | jq .data[] | select(.name=="TestAccount").id
curl --basic -u admin:admin http://XX.XX.XX.XX:8080/mmc-console-3.7.3/api/deployments | jq .data[] | select(.name==\"TestAccount\").id
Output
select is not recognized as an internal or external command
I have jq in my path but not sure what I have to add in my path so that it can recognize `select as a command.
You need to quote the JQ expression, e.g.:
curl --basic -u admin:admin http://XX.XX.XX.XX:8080/mmc-console-3.7.3/api/deployments | jq '.data[] | select(.name=="TestAccount").id'
Is it possible to use pastebin (may be via their "API" functionality) inside bash shell scripts? How do I send http-post? How do I get back the URL?
As pastebin.com closed their public api, I was looking for alternatives.
Sprunge is great. Usage:
<command> | curl -F 'sprunge=<-' http://sprunge.us
or, as I use it:
alias paste="curl -F 'sprunge=<-' http://sprunge.us"
<command> | paste
The documentation says that you need to submit a POST request to
http://pastebin.com/api_public.php
and the only mandatory parameter is paste_code, of type string is the paste that you want to make.
On success a new pastebin URL will be returned.
You can easily do this from your bash shell using the command curl.
curl uses the -d option to send the POST data to the specified URL.
Demo:
This demo will create a new paste with the code:
printf("Hello..I am Codaddict");
From your shell:
$ curl -d 'paste_code=printf("Hello..I am Codaddict");' 'http://pastebin.com/api_public.php'
http://pastebin.com/598VLDZp
$
Now if you see the URL http://pastebin.com/598VLDZp, you'll see my paste :)
Alternatively you can do it using the wget command which uses the option --post-data to sent POST values.
I've tried this command it works fine:
wget --post-data 'paste_code=printf("Hello..I am Codaddict");' 'http://pastebin.com/api_public.php'
Put the following in your .bashrc:
sprunge() {
if [[ $1 ]]; then
curl -F 'sprunge=<-' "http://sprunge.us" <"$1"
else
curl -F 'sprunge=<-' "http://sprunge.us"
fi
}
...and then you can run:
sprunge filename # post file to sprunge
...or...
some_command | sprunge # pipe output to sprunge
The API for posting to pastebin has changed, since posted by codaddict.
Details can be found at this link: https://pastebin.com/api
Example:
curl -d 'api_paste_code=printf("Hello..\n I am Codaddict");' \
-d 'api_dev_key=<get_your_own>' \
-d 'api_option=paste' 'http://pastebin.com/api/api_post.php'
There are three essential fields as of now:
api_dev_key -> You need to create a login on pastebin.com in order to get that
api_option -> Format in which to post
api_paste_code -> Text you want to post
Two other answers (from circa 2014) point to http://sprunge.us, which is designed to be used like this...
curl --form 'sprunge=#yourfile.txt' sprunge.us
However, as of 2018, sprunge.us has a tendency to be overloaded and return 500 Internal Server Error to every request. For files up to at least 300 KB but not as high as 2.8 MB, I have had good luck with the very similar service at http://ix.io:
curl --form 'f:1=#yourfile.txt' ix.io
For files up to at least 2.8 MB (and maybe higher, I don't know), I've found the more highly polished https://transfer.sh. It recommends a slightly different and simpler command line, and requires https (it won't work without it):
curl --upload-file yourfile.txt https://transfer.sh
I have found that Sprunge is currently down, but dpaste.com has a simple API.
To post from STDIN
curl -s -F "content=<-" http://dpaste.com/api/v2/
from a file foo.txt
cat foo.txt | curl -s -F "content=<-" http://dpaste.com/api/v2/
to post a string
curl -s -F "content=string" http://dpaste.com/api/v2/
The response will be a plain text URL to the paste.
Nb: the trailing / in the URL http://dpaste.com/api/v2/ seems necessary
https://paste.c-net.org/ has a simpler API than all of them. Simply "POST" to it.
From the website:
Upload text using curl:
$ curl -s --data 'Hello World!' 'https://paste.c-net.org/'
Upload text using wget:
$ wget --quiet -O- --post-data='Hello World!' 'https://paste.c-net.org/'
Upload a file using curl:
$ curl --upload-file #'/tmp/file' 'https://paste.c-net.org/'
Upload a file using wget:
$ wget --quiet -O- --post-file='/tmp/file' 'https://paste.c-net.org/'
Upload the output of a command or script using curl:
$ ls / | curl --upload-file - 'https://paste.c-net.org/'
$ ./bin/hello_world | curl -s --data-binary #- 'https://paste.c-net.org/'
You can also simply use netcat. Unlike termbin, paste.c-net.org won't time out if your script takes more than 5 seconds to produce its output.
$ { sleep 10; ls /; } | nc termbin.com 9999
$ { sleep 10; ls /; } | nc paste.c-net.org 9999

Easiest way to post to pastebin
echo 'your message' | sed '1s/^/api_paste_code=/g' | sed 's/$/\%0A/g' | curl -d #- -d 'api_dev_key=<your_api_key>' -d 'api_option=paste' 'http://pastebin.com/api/api_post.php'
Just change the <your_api_key> part and pipe whatever you want into it.
The sed invocations add the api_paste_code parameter to beginning of the message and add a newline at the end of each line so it can handle multiline input. The #- tells curl to read from stdin.
A Bash Function You Can Paste
For easy reuse, make it a bash function (copy and paste this into your terminal and set the API_KEY field appropriately:
pastebin () {
API_KEY='<your_api_key>'
if [ -z $1 ]
then
cat - | sed '1s/^/api_paste_code=/g' | sed 's/$/\%0A/g' | curl -d #- -d 'api_dev_key='"$API_KEY"'' -d 'api_option=paste' 'http://pastebin.com/api/api_post.php'
else
echo "$1" | sed '1s/^/api_paste_code=/g' | sed 's/$/\%0A/g' | curl -d #- -d 'api_dev_key='"$API_KEY"'' -d 'api_option=paste' 'http://pastebin.com/api/api_post.php'
fi
printf '\n'
}
You can run it with either:
pastebin 'your message'
or if you need to pipe a file into it:
cat your_file.txt | pastebin
To built upon Vishal's answer, pastebin has upgraded to only use HTTPS now:
curl -d 'api_paste_code=printf("Hello World");' \
-d 'api_dev_key=<your_key>' \
-d 'api_option=paste' 'https://pastebin.com/api/api_post.php'
You don't have to specify the -X POST parameter

Based on another answer on this page, I wrote the following script which reads from STDIN (or assumes output it piped into it).
This version allows for arbitrary data which is URI escaped (by jq).
#!/bin/bash
api_key=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
curl -d "api_paste_code=$(jq -sRr #uri)" \
-d "api_dev_key=$api_key" \
-d 'api_option=paste' 'https://pastebin.com/api/api_post.php'
echo # By default, there's no newline
I am a bit late to this post, but I created a little tool to help with this.
