参照20.03-sp1已发布的gala-gopher镜像的dockerfile，尝试在openeuler 20.03-sp2上构建gala-gopher镜像，有点问题咨询

如下是在openeuler 20.03-sp2上参照20.03-sp1已发布的gala-gopher镜像的dockerfile构建gala-gopher的动作，
构建过程中有一些报错提示信息，但最终还是生成了镜像，并可以通过镜像启动容器，麻烦帮忙看看这种构建过程是否可行，谢谢！

一 基础信息：

二 镜像构建过程：（有一些报错提示信息，但最终还是生成了镜像）由于error提示信息太多了，只附上了部分信息，共174条这种error: digest_list: could not apply security.ima on的提示信息

三 可以用刚生成的镜像启动容器
[root@localhost soft]# cat deploy1.sh |grep "function deploy_gopher_docker" -A16      参照实际情况更改了部分deploy.sh的代码，可以正常启动容器
function deploy_gopher_docker() {
    container_name="gala-gopher1"
    #gopher_tag="gala-gopher-${OS_ARCH}:${GOPHER_DOCKER_TAG}"

echo -e "\n[2] Creating gala-gopher container"

    [ $? -ne 0 ] && echo_err_exit "Error: fail to run gala-gopher container"
