Ingia, Piga & Tuma

# Docker login into ecr
## For public repo (always use us-east-1)
aws ecr-public get-login-password --region us-east-1 | docker login --username AWS --password-stdin public.ecr.aws/<random-id>
## For private repo
aws ecr get-login-password --profile <profile_name> --region <region> | docker login --username AWS --password-stdin <account_id>.dkr.ecr.<region>.amazonaws.com
## If you need to acces an image from a repo if a different account, in <account_id> set the account number of the other account

# Download
docker pull <account_id>.dkr.ecr.<region>.amazonaws.com/<img_name>:latest
## If you still have the error "Requested image not found"
## It might be because the tag "latest" doesn't exit
## Get valid tags with:
TOKEN=$(aws --profile <profile> ecr get-authorization-token --output text --query 'authorizationData[].authorizationToken')
curl -i -H "Authorization: Basic $TOKEN" https://<account_id>.dkr.ecr.<region>.amazonaws.com/v2/<img_name>/tags/list

# Inspect the image
docker inspect sha256:079aee8a89950717cdccd15b8f17c80e9bc4421a855fcdc120e1c534e4c102e0

# Upload (example uploading purplepanda with tag latest)
docker tag purplepanda:latest <account_id>.dkr.ecr.<region>.amazonaws.com/purplepanda:latest
docker push <account_id>.dkr.ecr.<region>.amazonaws.com/purplepanda:latest

# Downloading without Docker
# List digests
aws ecr batch-get-image --repository-name level2 \
--registry-id 653711331788 \
--image-ids imageTag=latest | jq '.images[].imageManifest | fromjson'

## Download a digest
aws ecr get-download-url-for-layer \
--repository-name level2 \
--registry-id 653711331788 \
--layer-digest "sha256:edfaad38ac10904ee76c81e343abf88f22e6cfc7413ab5a8e4aeffc6a7d9087a"

ecr:PutLifecyclePolicy | ecr:DeleteRepository | ecr-public:DeleteRepository | ecr:BatchDeleteImage | ecr-public:BatchDeleteImage

Mshambuliaji mwenye mojawapo ya ruhusa hizi anaweza kuunda au kurekebisha sera ya mzunguko wa maisha ili kufuta picha zote kwenye hifadhi na kisha kufuta hifadhi nzima ya ECR. Hii itasababisha upotevu wa picha zote za kontena zilizohifadhiwa kwenye hifadhi.
