Github action runner sending log messages to loki

Grafana Loki
,
1

Hi,
I was looking for a way to send logs from github action runners to loki, running as part of our grafana enterprise installation.

I was able to do it using curl, but it would be much better to have an action defined which abstracts away all the detail.

Does anyone happen to know of, or has written an action?

I found an action called “loki-action” but it wasn’t what I wanted at all.

thanks for any thoughts.

FYI, this is the curl command needed

          AWS_ACCOUNT=my-aws-account &&
          AWS_REGION=us-east-1 &&
          LOKI_URL="https://loki.example.com/loki/api/v1/push" &&
          OS_PRETTY_NAME=$( awk -F= '/PRETTY_NAME=/{print $2}' )
          RUNNER_IP=$(  ip ad | grep -A 2 "^2" | awk '/inet/{print $2}' ) &&
          tod_ymdhms=$( date +%Y%m%d-%H%M%S) &&
          tod_nanos=$( date +%s)000000000 &&
          curl    -u "${LOKI_TENANT}:${LOKI_PASSWORD}" \
                  -i \
                  -H "Content-Type: application/json" \
                  -H "X-Scope-OrgID:$LOKI_TENANT" \
                  -XPOST \
                  -s "${LOKI_URL}" \
                  --data-raw "{\"streams\": [{ \"stream\": { \"aws_account\": \"$AWS_ACCOUNT\", \"Product\": \"$LOKI_TENANT\", \"log_level\":\"info\", \"region\": \"$AWS_REGION\", \"repo_name\":\"$GITHUB_REPOSITORY\", \"repo_owner\":\"$GITHUB_REPOSITORY_OWNER\", \"github_server_url\":\"$GITHUB_SERVER_URL\", \"runner_hostname\":\"$HOSTNAME\", \"runner_ip\":\"$RUNNER_IP\", \"runner_name\":\"$RUNNER_NAME\", \"runner_os\":\"$RUNNER_OS\", \"runner_os_name\":\"$OS_PRETTY_NAME\", \"runner_type\":\"self_docker\", \"target\":\"github-inventories\", \"workflow_name\":\"$GITHUB_WORKFLOW\", \"workflow_trigger\":\"$GITHUB_TRIGGERING_ACTOR\", \"ymdhms\":\"$tod_ymdhms\" }, \"values\": [ [ \"$tod_nanos\", \"$message\" ] ] }]}"

I am not familiar with GitHub action, but if there isn’t one for Loki / Grafana cloud you could potentially write your own. But then it’ll probably be a bit more involved than just using curl (from the doc it looks like it’s nodejs?)

So far it’s looking like I might have to write my own action, fortunately there’s a decent amount of documentation, and examples I can cargo-cult to that end.
