k8s安装nettools

1.拉取nettools镜像

[root@localhost app]# docker search nettools
INDEX       NAME                                  DESCRIPTION                                     STARS     OFFICIAL   AUTOMATED

...                   

[root@localhost app]# docker pull docker.io/travelping/nettools 

[root@localhost app]# docker images
REPOSITORY                          TAG                 IMAGE ID            CREATED             SIZE
docker.io/travelping/nettools       latest              2d2c7dadefe0        3 years ago         23.8 MB

2.将镜像打标签

docker tag 2d2c7dadefe0 10.10.10.10/images/app:20231031

3.上传到镜像仓库（镜像仓库自己去阿里云创建）

[root@localhost app]# docker push 10.10.10.10/images/app:20231031
The push refers to a repository [10.189.4.241/gd-yares/app]

4.k8s环境拉取镜像

vim deployment.yaml
