![]() My CentOS 7 headless install of Dropbox recently quit syncing due to the new Dropbox linux requirements. This network bridge allows virtual machines to have access to the external network and vice-versa, follow this guide to setup network bridge on CentOS 7 / RHEL 7. Rather than try to hack it back together I found this great guide on running Dropbox in a Docker container which utilizes a pre-built container that can update itself, assuming Dropbox puts any more effort into their linux client. This manual explains how to boot the CentOS 7 installation program (Anaconda) and how to install CentOS 7 on AMD64 and Intel 64 systems, 64-bit ARM systems, and 64-bit IBM Power Systems servers.It also covers advanced installation methods such as Kickstart installations, PXE installations, and installations over VNC. CentOS 7 comes with bridging module loaded on system boot by default. Use the following command to verify whether the module is loaded or not. You can audit the security/operation of the container via its Dockerfile. The name "dropbox" is already in use by container f9e5798a82e9 However one thing both the guide docs and container docs above leave out is automating operation of the Dropbox container via systemd, which of course is the default init system most places nowadays including my CentOS 7 and Ubuntu 18.04 bionic servers. This is because all the guides suggest using the Docker parameter -name=dropbox which will only succeed the first time you issue the docker run command. When you restart the container via run instead of start it instructs docker to build a new container. Rebuilding the container is also when the Dockerfile would update to the latest version of Dropbox so we can't simply switch to start. To get around this we use the systemd directive ExecStartPre=-/usr/bin/docker rm dropbox to remove any previous containers using the name dropbox, and additionally prefix the command with a - which tells systemd to ignore any failures reported by the command. A user can download and use this enterprise-level operating system free of cost.Advertisement The CentOS project has announced a new update to the distribution, releasing CentOS 7.9 which is derived from Red Hat Enterprise Linux 7.9. Ie: if there is no container to remove docker reports an error we don't care about. This guide will help you setup a local CentOS 7 YUM repository locally in your Server / Desktop machine. CentOS is a Linux operating system, which is a 100 compatible rebuild of the Red Hat Enterprise Linux. ![]()
