# Any unique sequence of characters would work as a CI build image | |
# tag, but an ISO-8601 date without separators would be the easiest | |
# to maintain. In a rare case when more than one image needs to | |
# be built in one day, a sequence suffix may be added: 20220526.1 | |

# we can either create prefix/suffix strings to combine all bits | |
# later or use a format, so at least it is clear where goes what. | |
