#!/bin/bash # This Docker ENTRYPOINT script is called by `docker run archivebox ...` or `docker compose run archivebox ...`. # It takes a CMD as $* shell arguments and runs it following these setup steps: # - Set the archivebox user to use the correct PUID & PGID # 1. highest precedence is for valid PUID and PGID env vars passsed in explicitly # 2. fall back to DETECTED_PUID of files found within existing data dir # 3. fall back to DEFAULT_PUID if no data dir or its owned by root # - Create a new /data dir if necessary and set the correct ownership on it # - Create a new /browsers dir if necessary and set the correct ownership on it # - Check whether we're running inside QEMU emulation and show a warning if so. # - Check that enough free space is available on / and /data # - Drop down to archivebox user permisisons and execute passed CMD command. # Bash Environment Setup # http://redsymbol.net/articles/unofficial-bash-strict-mode/ # https://www.gnu.org/software/bash/manual/html_node/The-Set-Builtin.html # set -o xtrace # set -o nounset set -o errexit set -o errtrace set -o pipefail # IFS=$'\n' # Load global invariants (set by Dockerfile during image build time, not intended to be customized by users at runtime) export DATA_DIR="${DATA_DIR:-/data}" export ARCHIVEBOX_USER="${ARCHIVEBOX_USER:-archivebox}" # Global default PUID and PGID if data dir is empty and no intended PUID+PGID is set manually by user export DEFAULT_PUID=911 export DEFAULT_PGID=911 # If user tires to set PUID and PGID to root values manually, catch and reject because root is not allowed if [[ "$PUID" == "0" ]];
