我想使用.rpm文件在RHEL 7.3上安装Docker镜像。
我可以访问Docker .rpm文件,但是稳定包中有文件列表。
任何人都可以让我知道我应该使用哪个.rpm文件进行安装。

您可以从dockerhub portal搜索现成的RHEL docker镜像;并将其拉为// you need these includes for the function
//#include <windows.h> // for windows systems
#include <dirent.h> // for linux systems
#include <sys/stat.h> // for linux systems
#include <algorithm> // std::sort
#include <opencv2/opencv.hpp>
#include <iostream> //cout
using namespace std;
/* Returns a list of files in a directory (except the ones that begin with a dot) */
int readFilenames(std::vector<string> &filenames, const string &directory)
{
#ifdef WINDOWS
HANDLE dir;
WIN32_FIND_DATA file_data;
if ((dir = FindFirstFile((directory + "/*").c_str(), &file_data)) == INVALID_HANDLE_VALUE)
return; /* No files found */
do {
const string file_name = file_data.cFileName;
const string full_file_name = directory + "/" + file_name;
const bool is_directory = (file_data.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) != 0;
if (file_name[0] == '.')
continue;
if (is_directory)
continue;
filenames.push_back(full_file_name);
} while (FindNextFile(dir, &file_data));
FindClose(dir);
#else
DIR *dir;
class dirent *ent;
class stat st;
dir = opendir(directory.c_str());
while ((ent = readdir(dir)) != NULL) {
const string file_name = ent->d_name;
const string full_file_name = directory + "/" + file_name;
if (file_name[0] == '.')
continue;
if (stat(full_file_name.c_str(), &st) == -1)
continue;
const bool is_directory = (st.st_mode & S_IFDIR) != 0;
if (is_directory)
continue;
// filenames.push_back(full_file_name); // returns full path
filenames.push_back(file_name); // returns just filename
}
closedir(dir);
#endif
std::sort (filenames.begin(), filenames.end()); //optional, sort the filenames
return(filenames.size()); //Return how many we found
} // GetFilesInDirectory
void help(const char **argv) {
cout << "\n\n"
<< "Call:\n" << argv[0] << " <directory path>\n\n"
<< "Given a directory of images, create a vector of\n"
<< "their names, read and display them. Filter out\n"
<< "non-images\n"
<< endl;
}
int main( int argc, const char** argv )
{
if(argc != 2) {
cerr << "\nIncorrect number of parameters: " << argc << ", should be 2\n" << endl;
help(argv);
return -1;
}
string folder = argv[1];
cout << "Reading in directory " << folder << endl;
vector<string> filenames;
int num_files = readFilenames(filenames, folder);
cout << "Number of files = " << num_files << endl;
cv::namedWindow( "image", 1 );
for(size_t i = 0; i < filenames.size(); ++i)
{
cout << folder + filenames[i] << " #" << i << endl;
cv::Mat src = cv::imread(folder + filenames[i]);
if(!src.data) { //Protect against no file
cerr << folder + filenames[i] << ", file #" << i << ", is not an image" << endl;
continue;
}
cv::imshow("image", src);
cv::waitKey(250); //For fun, wait 250ms, or a quarter of a second, but you can put in "0" for no wait or -1 to wait for keypresses
/* do whatever you want with your images here */
}
}
。
或者,您可以按照以下方式构建自己的RHEL。
docker pull <image-name>
修改mkimage-yum.sh以创建一个rhel 7最小tarfile,注释掉最后两行/三行(如下所示)并添加一个新行,如下所示:
https://github.com/docker/docker/blob/master/contrib/mkimage-yum.sh
将脚本设为#tar –numeric-owner -c -C "$target" . | docker import - $name:$version
#docker run -i -t $name:$version echo success
tar --numeric-owner -c -C "$target" . -zf ${name}.tar.gz
。
将tar文件中的docker镜像构建为./mkimage-yum.sh rhel7_docker
cat rhel7_docker.tar.gz | sudo docker import - rhel7

要从.rpm文件安装docker,您需要下载rpm文件并使用YUM进行安装。我是为Docker Enterprise版做的。我将稳定包中的rpm文件从docker storebits下载到我的本地文件夹。我们需要selinux和docker-ee rpm文件。然后将YUM安装目录指向下载文件夹。 注意首先安装Selinux rpm,然后安装docker-ee rpm
yum install&#34; rpm文件的路径&#34;
