Utilizing Docker shared-storage volume plugins for Docker data volume to persist container data. Example: docker run -interactive -tty -read-only -v /opt/app/data:/run/app/data:rw 3. Enabling Docker rw mounts at a container's runtime to persist container data directly on the Docker host filesystem. Discourse 8A installed in a Convoy Categories in common with Discourse. Example: docker run -interactive -tty -read-only -tmpfs '/run' -tmpfs '/tmp' 2. On April 6th, 2020 we dropped However, if neither Docker nor subscription fees. Use the -tmpfs option to mount a temporary file system for non-persistent data writes. Examples of explicit storage locations during a container's runtime include, but are not limited to: 1. docker run -read-only Enabling the -read-only option at a container's runtime should be used by administrators to force a container's executable processes to only write container data to explicit storage locations during the container's runtime. Convoy used Docker volume plugin mechanism to provide persistent volume for Docker containers, and supports various of backends(e.g. Solution Add a -read-only flag at a container's runtime to enforce the container's root filesystem to be mounted as read only. Example: - Enable use -tmpfs for temporary file writes to /tmp - Use Docker shared data volumes for persistent data writes By default, a container will have its root filesystem writable allowing all container processes to write files owned by the container's runtime user. Define what the container's data should and should not persist at runtime to determine which recommendation procedure to utilize. Enabling -read-only at container runtime may break some container OS packages if a data writing strategy is not defined. This also reduces security attack vectors since the container instance's filesystem cannot be tampered with or written to unless it has explicit read-write permissions on its filesystem folder and directories. Enabling this option forces containers at runtime to explicitly define their data writing strategy to persist or not persist their data. This prevents any writes to the container's root filesystem at container runtime and enforces the principle of immutable infrastructure. Information The container's root filesystem should be treated as a 'golden image' by using Docker run's -read-only option.
