.SH "NAME"
debspawn-update \- Update a container image
.SH "SYNOPSIS"
.HP \w'\fBdebspawn\ update\fR\ 'u
\fBdebspawn update\fR [\-h|\-\-help] [\-\-variant] [\-a|\-\-arch] {SUITE}
.SH "DESCRIPTION"
.PP
Update a container base image\&. This achieves the same thing as running
\fBapt update && apt full\-upgrade\fR
on the base image and making the changes permanent\&. Additionally,
\fBdebspawn update\fR
will prune all caches and ensure all required packages and scripts are installed in the container image\&.
.PP
Running
\fBdebspawn update\fR
on the images that are in use about once a week ensures builds will happen faster, due to less changes that have to be done prior to each build\&.
.SH "EXAMPLES"
.PP
Updating images is easy, you just pass the same arguments you used for creating them, but use the
\fBupdate\fR
subcommand instead:
.sp
.if n \{\
.RS 4
.\}
.nf
			$ \fBdebspawn update\fR sid
			$ \fBdebspawn update\fR \-\-arch=i386 cosmic
		
.fi
.if n \{\
.RE
.\}
.SH "OPTIONS"
