pretty print docker ps commands

    astdout, astderr = a.communicate()

    data = astdout.split("\n")
    data = filter(None, data)
    header = re.split(r'\s{2,}', data[0])
    rows = data[1:]

    for row in rows:
        print json.dumps(dict(zip(header, row)), indent=4)

I've been using this, it can be put into your .bash_profile or .bashrc file that works somewhat like an alias for docker ps. The output has color distinctions as well:

usage: $ docker ps -p

function docker () {
    if [[ "$@" == "ps -p" ]]; then
        command docker ps --all --format "{{.ID}}\t{{.Names}}\t{{.Image}}\t{{.Ports}}\t{{.Status}}" \
            | (echo -e "CONTAINER_ID\tNAMES\tIMAGE\tPORTS\tSTATUS" && cat) \
            | awk '{printf "\033[1;32m%s\t\033[01;38;5;95;38;5;196m\%s\t\033[00m\033[1;34m%s\t\033[01;90m%s %s %s %s %s %s %s\033[00m\n", $1, $2, $3, $4, $5, $6, $7, $8, $9, $10;}' \
            | column -s$'\t' -t
    else
        command docker "$@"
    fi
}
