[Docker] Docker image registry Harbor
Harbor? 내가 직접 관리하는 Docker 이미지 저장소. 도커 Harbor(하버)는 컨테이너 이미지를 안전하게 저장, 관리, 스캔, 복제하는 엔터프라이즈급 오픈소스 컨테이너 이미지 레지스트리이다. Docker Hub 같은 공개 저장소와 달리 기업 내부 서버(Private)에 설치하여 보안(RBAC), 이미지 취약점 검색, 역할 기반 접근 제어 등을 제공하는 핵심 DevOps 도구이다. Registry : 대상이 되는 것을 저장·공유하는 저장소 Harbor는 대표적인 Private registry open source이다. Container Image 저장 외 여러가지 기능을 제공한다. Container Image에 대한 보안 및 취약점을 분석해준다.

docker使用Open Policy Agent(OPA)进行访问控制
本文主要基于Docker version 20.10.16和Linux操作系统Ubuntu 18.04。 服务器版本 docker软件版本 CPU架构 Ubuntu 18.04.5 LTS Docker version 20.10.16 x86_64 在容器化技术中,Docker 已经成为广泛使用的工具。然而,随着容器数量的增加,确保容器之间的安全隔离变得越来越重要。Docker 提供了各种安全特性,但有时我们可能需要更细粒度的访问控制策略。Open Policy Agent(OPA)是一个开源的通用策略引擎,可以与 Docker 集成,以实现更灵活的访问控制。本文将介绍如何在 Docker 中使用 OPA 进行访问控制。 OPA 是一个开源的通用策略引擎,可以评估策略并做出决策。OPA 可以应用于各种场景,例如网络安全、访问控制、数据保护等。在 Docker 环境中,OPA 可以用于评估容器之间的访问请求,并根据预定义的策略做出决策,Open Policy Agent(OPA)的官网为:https://www.openpolicyagent.org/。 虽然 Docker...

How To Add More SWAP Space To Linux The Easy Way
Alright, so before we continue with the fun part, we have to address what we need to know about SWAP space. The catch is that you have to sacrifice disk space from your hard drive. How much disk space? Ehh that can differ depending on what you have going on inside your system. Let’s look at what our friends at Fedora have to say about this. Using a SWAP File can actually be detrimental in some cases. Why?

27. Ubuntu 20.04 开机自动挂载文件/etc/fstab
不同于热插拔的设备,对于硬盘可能需要长期挂载在系统下,所以如果每次开机都去手动mount是非常痛苦的,当然Ubuntu系统的GNOME桌面自带的gvfsd也会帮你自动挂载,但是指向的路径却是按照uuid命名的,这是极其痛苦的,所以希望开机就可以自动挂载硬盘到指定路径。 系统开机的时候会读取/etc/fstab这个文件中的内容,根据文件配置情况去挂载磁盘。 vim /etc/fstab,打开fstab文件,具体如下图所示; fstab信息 vim /etc/fstab UUID=37a0fcfb-d9f1-4e70-bdaa-b40a10945de5 / ext4 errors=remount-ro 0 1 UUID=EBE5-4E92 /boot/efi vfat umask=0077 0 1 /swapfile none swap sw 0 0 ~ ~ 这里需要配置6个参数, # <file system> <mount point> <type> <options> <dump> <pass> # <设备文件名称> <挂载目录> <文件系统类型> <文件系统参数>...

设定docker容器的磁盘大小_docker设置磁盘大小_周洋宇杰的博客-CSDN博客
查找到资料可以对docker容器磁盘大小进行设置,已知方法有两种,基于xfs文件系统的和devicemapper设置的,对比了一下,基于xfs方式的更适合,下面开始操作: 由于我系统是ubuntu18的。默认文件系统是ext4,所以我先把一块磁盘转为xfs: cat /etc/fstab 查看文件系统格式 umount -v /home 取消磁盘挂载 或者 umount -v /dev/sdb mkfs.xfs -f /dev/sdb 格式化为xfs mount -o pquota,prjquota /dev/sdb /data/ 挂载到/data/目录 这里挂载配额类型如下: 根据用户(uquota/usrquota/quota) 根据组(gquota/grpquota) ; 根据目录(pquota/prjquota)(不能与grpquota同时设定) 然后参看cat /etc/fstab # /etc/fstab: static file system information.
Web Application Security: From Vulnerabilities to Monitoring
Web application vulnerabilities appear when developers add unsafe code to a web application. It can happens both in the development stage, and in the stage of finalizing or fixing previously found vulnerabilities. Disadvantages are often classified according to their severity and prevalence. The OWASP Top 10 is considered to be the most popular and objective vulnerability classification. This rating is compiled by OWASP Project specialists and updated every 3–4 years.
