[Docker] Comand Docker hay quên!!

1) Docker

Show log 10 dòng cuối:

docker logs -f --tail 10 container_name

Docker build

docker build -t ps:version1 --force-rm -f Dockerfile .

kubectl -n argocd port-forward deployment.apps/argocd-server 8080:8080

với các build mà sử dụng git private:

GITHUB_TOKEN=abcsldfnjsdbfasd

docker build -t ps:version1 --force-rm --build-arg GITHUB_TOKEN=${GITHUB_TOKEN} -f Dockerfile.ci .

trong Dockerfile thì bạn sẽ có dòng RUN như sau:

Host key verification failed.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
error building image: error building stage: failed to execute command: waiting for process to exit: exit status 1

Nếu bạn bị lỗi trên thì thêm line bên dưới vào dockerfile

RUN git config --global url."https://${GITHUB_TOKEN}:x-oauth-basic@github.com/".insteadOf "https://github.com/"

2) Docker-compose

Run docker-compose chỉ định file:

docker-compose -f docker-compose.test.yml up

3) Docker images

docker save --output myimage.tar myimage_id
>>>>Lưu image ra đĩa
docker load -i myimage.tar
>>>>Nạp Image trên đĩa vào Docker
docker tag image_id imagename:version
>>>>Đổi tên Image

4) Build image, Write Dockerfile
