Not able to build docker image in gitlab CI - docker

Question

Been trying to build a simple gitlab CI pipeline which builds an image and pushes it to Google container repository. I am running through this error -
ERROR: error during connect: Get "http://docker:2375/v1.24/info": dial
tcp: lookup docker on 169.254.169.254:53: no such host
I have tried all the solutions posted across gitlab issues threads but no help. I am using public runners, it's a pretty simple ci script.
image: docker:latest
variables:
GCR_IMAGE: <GCR_IMAGE>
services:
- docker:dind
build:
stage: build
before_script:
- docker info
- echo $GOOGLE_CLOUD_ACCOUNT | docker login -u _json_key --password-stdin https://us.gcr.io
script:
- docker build -t $GCR_IMAGE:latest .
- docker push $GCR_IMAGE:$CI_COMMIT_SHA

A few weeks ago I encountered this problem and was able to solve it with this method:
image:
name: docker:20.10.16
services:
- name: docker:20.10.16-dind
variables:
DOCKER_HOST: tcp://docker:2376/
DOCKER_TLS_CERTDIR: "/certs"
DOCKER_TLS_VERIFY: 1
DOCKER_CERT_PATH: "$DOCKER_TLS_CERTDIR/client"
before_script:
- until docker info; do sleep 1; done
- echo $GOOGLE_CLOUD_ACCOUNT | docker login -u _json_key --password-stdin https://us.gcr.io
script:
- docker build -t $GCR_IMAGE:latest .
- docker push $GCR_IMAGE:$CI_COMMIT_SHA
Also add this configuration to runner
[[runners]]
[runners.kubernetes]
namespace = "{{.Release.Namespace}}"
image = "ubuntu:20.04"
[[runners.kubernetes.volumes.empty_dir]]
name = "docker-certs"
mount_path = "/certs/client"
medium = "Memory"
