Block external access to docker containers

由 浪尽此生 提交于 2019-12-20 07:20:12
问题 I would like to block direct access to the docker containers from outside. I use a haproxy and want to only allow access to port 80, 443. I added the following rule to iptables. But I still can access docker containers through different ports. *filter :INPUT DROP [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT -A INPUT -p

问题 I have been struggling lately on installing latest nginx 1.14, php 7.2.5 and mariaDB 10.3.7 on CentOS 7 on virtualbox on macOS. Finally php is working, I have already tested php_info() , index.php , testDBconnection.php successfully and even redirecting to a /public folder. However, when copying my Slim 3 application to folder, I get this error: access denied I access the log via # tail /var/log/nginx/error.log and the output is the following: PHP message: PHP Warning: session_start(): Failed

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 1. 文中符号的说明： <A/B>: 可以理解成A，也可以理解成B。 2. 术语 调制解调器(Modem): 实现模拟信号与数字信号间的相互转换，可以忽略成一条网线。 路由器: 提供路由、DHCP、NAT等<功能/服务>的专门设备，连接不同的网络(包括局域网与WAN之间的连接，提供互联网连接)。 网关: 网关实质上是一个网络通向其他网络的IP地址。比如有网络A和网络B，网络A的IP地址范围为“192.168.1.1~192. 168.1.254”，子网掩码为255.255.255.0；网络B的IP地址范围为“192.168.2.1~192.168.2.254”，子网掩码为255.255.255.0。在没有路由器的情况下，两个网络之间是不能进行TCP/IP通信的，即使是两个网络连接在同一台交换机（或集线器）上，TCP/IP协议也会根据子网掩码（255.255.255.0）判定两个网络中的主机处在不同的网络里。而要实现这两个网络之间的通信，则必须通过网关。如果网络A中的主机发现数据包的目的主机不在本地网络中，就把数据包转发给它自己的网关，再由网关转发给网络B的网关，网络B的网关再转发给网络B的某个主机。只有设置好网关的IP地址，TCP/IP协议才能实现不同网络之间的相互通信。那么这个IP地址是哪台机器的IP地址呢

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 3 years ago . I have a file that is very large (>500GB) that I want to prepend with a relatively small header (<20KB). Doing commands such as: cat header bigfile > tmp mv tmp bigfile or similar commands (e.g., with sed) are very slow. What is the fastest method of writing a header to the
