Mirrors and Binary Caches Tutorial¶
This tutorial will guide you through the process of setting up a source mirror with a binary cache. Source mirrors and binary caches are extremely useful when using spack on a machine without internet access. Source mirrors allow you to fetch source code from a directory on your filesystem instead of accessing the outside internet, and binary caches allow you to install pre-compiled binaries to your spack installation path. Together, these two features can speed up builds when using spack within a larger development team.
We will use the filesystem for the mirrors in this tutorial, but
mirrors can also be setup on web servers or s3 buckets – any URL that
curl can access can be setup as a Spack mirror.
By default, Spack comes configured with a source mirror in the cloud to increase download reliability. We’ve also already set up a mirror in this tutorial for binary caches. We can see these mirrors are configured
$ spack mirror list
tutorial file:///mirror
spack-public https://mirror.spack.io
Setting up a source cache mirror¶
When you run spack install, spack goes out to the internet to grab
the source code to build your packages. This works fine on most
clusters, but what do you do if the cluster in question doesn’t have
access to the outside internet? This could happen for a variety of
reasons. Maybe you’re building on a compute node that isn’t connected
to the greater internet, or maybe even the whole cluster has been
isolated from the internet.
Spack has an easy answer to this – setting up a source mirror. When you use a source mirror, spack checks the mirror for the source code before going to the outside internet.
Building a source mirror is easy. Let’s start with the same simple environment. First, let’s build our software on a computer with external internet access.
$ cd ~
$ mkdir cache-env
$ cd cache-env
$ spack env create -d .
==> Created environment in /home/spack/cache-env
==> You can activate this environment with:
==> spack env activate /home/spack/cache-env
$ spacktivate .
$ # for now, disable fortran support in all packages
$ spack config add "packages:all:variants: ~fortran"
$ spack add macsio+scr
==> Adding macsio+scr to environment /home/spack/cache-env
$ spack install
==> Starting concretization
==> Environment concretized in 21.00 seconds.
==> Concretized macsio+scr

==> Installing environment /home/spack/cache-env
==> All of the packages are already installed
Once we’ve created and installed this environment, we can easily
upload source code needed to reproduce this build to a mirror. The
following command both creates the mirror and uploads the source code
for the scr package included in our environment. The -d flag
(short for --directory) tells spack where to place the mirrored
source code files.
$ spack mirror create -d ~/mirror scr

==> Fetching https://mirror.spack.io/_source-cache/archive/47/471978ae0afb56a20847d3989b994fbd680d1dea21e77a5a46a964b6e3deed6b.tar.gz
==> Successfully created mirror in file:///home/spack/mirror
Archive stats:
0 already present
1 added
0 failed to fetch.
We can configure spack to use this source mirror by adding
a few lines to your spack.yaml file.
$ spack mirror add mymirror ~/mirror
Manually uploading every package in an environment can be
tedious. Luckily, when run within an environment, spack mirror
create with the --all flag will upload every source used to build
the current environment to the specified directory.
$ spack mirror create -d ~/mirror --all

This directory can be shared between users on a shared filesystem and
protected with typical unix file permissions. If you’re making a spack
mirror on a shared filesystem, remember to fix the file permissions
every time you update the mirror, or update your
umask settings
so any new files you create have the appropriate permissions. Here you
would replace the word spack to the appropriate unix group.
$ umask 750
$ chmod -R g+rs ~/mirror
$ chgrp -R spack ~/mirror
As long as spack can read from the mirror directory, spack will attempt to read source packages from the mirror instead of accessing the internet. This can be a huge boon for computers that can’t access the external internet but can access a shared filesystem. If you need to use spack on a system that is isolated from the external internet, you must bundle the whole spack mirror directory and unbundle it on the isolated system. From there, you follow the same steps to use the spack mirror as you would on any computer that can’t access the external internet.
If you need to add more sources to the mirror, you can re-run the
command you used to create the mirror. For example, assume we want to
add unzip to our environment.
$ spack add unzip
==> Adding unzip to environment /home/spack/cache-env
$ spack install
==> Starting concretization

Spack will skip uploading source code packages that are already included in the spack mirror. Mirrors can be shared across different environments, meaning one mirror can house all the source code needed to build your team’s dependencies.
Setting up a binary cache mirror¶
If you’re going to be setting up a team to use spack as part of their development practice, you’ll run up against the biggest disadvantage to using spack: building all your packages from scratch is slow. Recompiling the software dependencies for a large project can take hours to complete. If every developer is rebuilding their own software stack, that leads to a massive waste of computational resources and a loss of developer productivity.
Spack has two ways to help alleviate this problem: chained spack instances and spack binary caches. For now, we’re going to discuss spack binary caches as a way of solving this issue.
A spack binary cache is made up of spack binary packages. Each spack
binary package, ending with a *.spack extension, is a tarball of an
installed spack package signed with a gpg signature. When you install
a package from a mirror with a binary cache, spack
- Checks to see if there is a spack binary package that exactly matches the hash of the spec you want to build.
- If a binary package is found, spack checks to see if the signature on the spack binary package is trusted. If the signature isn’t trusted or no package was found, spack builds the package from source.
- If the signature is trusted, then spack unzips and relocates the spack package.
For the user, spack binary caches are transparent to use. This is a clear departure from systems like conda, where you need to chose separate workflows for binary and source packages. We’ve already demonstrated using spack binary caches earlier in the tutorial when we set up spack to use a binary mirror. As a reminder, we ran:
$ spack mirror add tutorial /mirror
$ spack buildcache keys --install --trust
gpg: key A8E0CA3C1C2ADA2F: 7 signatures not checked due to missing keys
gpg: key A8E0CA3C1C2ADA2F: public key "Spack Project Official Binaries <maintainers@spack.io>" imported
gpg: Total number processed: 1
gpg: imported: 1
gpg: no ultimately trusted keys found
gpg: inserting ownertrust of 6
Building a spack binary cache has some gotchas, but is almost as easy as building a source mirror. We’ll start by making a new environment for ourselves. Since we’re intending to publish to a binary cache, we’ll need to compile all these packages ourselves. This can take some time, so we’ll make a new environment with some packages that compile quickly.
$ cd ~
$ mkdir cache-binary
$ cd cache-binary
$ spack env create -d .
==> Created environment in /home/spack/cache-binary
==> You can activate this environment with:
==> spack env activate /home/spack/cache-binary
$ spacktivate .
$ spack add bzip2
==> Adding bzip2 to environment /home/spack/cache-binary
$ spack add zlib
==> Adding zlib to environment /home/spack/cache-binary
Before we build anything, we need to modify the following line in our spack configuration file. Then, just to be sure, we’ll initiate a build of this environment and force ourselves to not use any cache.
$ spack config add "config:install_tree:padded_length:128"
$ spack install --no-cache

This configuration change ensures that spack installs all our packages to a path that is at least 128 characters. We need this change because of how spack relocates packages. Relocation consists of the following steps:
- Search all text files to replace the package builder’s path with your specific local installation path.
- Use
patchelfto replace all the RPATHs in your binaries to point to your specific local installation path.- Search all binaries to replace hard-coded C strings of the package builder’s path with your specific local installation path.
Adding padding ensures that any paths hard-coded as C strings in our binaries will be large enough to hold our user’s eventual install path. We advise picking 128 because longer strings occasionally cause compilation problems with some software packages. If the user’s install path is too long, spack will give you a warning. All scripts and and RPATHs will still be properly relocated, but C strings within any binaries will not be modified. Depending on the package, this may cause problems when you try and use the software.
We also need to create a gpg key to sign all our packages. You should back up the secret and public keys to a secure place so they can be re-used in the future.
$ spack gpg create "My Name" "<my.email@my.domain.com>"
gpg: key 718DD98D63235873 marked as ultimately trusted
gpg: directory '/home/spack/spack/opt/spack/gpg/openpgp-revocs.d' created
gpg: revocation certificate stored as '/home/spack/spack/opt/spack/gpg/openpgp-revocs.d/A74BD2559C7EAFFF1B48ECAC718DD98D63235873.rev'
$ mkdir ~/private_gpg_backup
$ cp ~/spack/opt/spack/gpg/*.gpg ~/private_gpg_backup
$ cp ~/spack/opt/spack/gpg/pubring.* ~/mirror
With this setup done, we’re ready to fill a binary cache with binary
packages. Binary packages are attached to an existing source mirror.
We follow the same steps we used for the source mirror – making an
environment, creating the source mirror, and building the packages to
a spack installation with our padded path. To upload a spec to a
binary cache, simply use the command spack buildcache
create --only=package spec. We use this here in a for loop to create
binary packages for every non-external package in our environment. We
do this by writing a find command that will return a hash of each spec
in this environment and filtering out the external packages.
$
for ii in $(spack find --format "yyy {version} /{hash}" |
grep -v -E "^(develop^master)" |
grep "yyy" |
cut -f3 -d" ")
do
spack buildcache create --allow-root --force -d ~/mirror --only=package $ii

Voila, done! Our spack mirror has now been augmented with a binary cache. This cache can be used on systems without external internet access, just like with a spack source mirror. As always, remember to update the file permissions after updating the mirror.
$ umask 750
$ chmod -R g+rs ~/mirror
$ chgrp -R spack ~/mirror
Though it’s outside the scope of this tutorial, spack mirrors and
build caches can also be hosted over https:// and s3:// as
well. Consult the spack documentation for more information on how to
do this.
Before a user can use this binary cache, they will need to make sure that they trust all the packages listed in the binary cache. If you’re sharing files between trusted users on a filesystem, you can do this with the following command:
$ spack buildcache keys --install --trust --force
==> Fetching file:///mirror/build_cache/_pgp/2C8DD3224EF3573A42BD221FA8E0CA3C1C2ADA2F.pub
gpg: key A8E0CA3C1C2ADA2F: 7 signatures not checked due to missing keys
gpg: key A8E0CA3C1C2ADA2F: "Spack Project Official Binaries <maintainers@spack.io>" not changed
gpg: Total number processed: 1
gpg: unchanged: 1
Together, this means download all the keys on the binary cache and trust them. Have your users run the above command on a new spack instance before they initiate a build.
Cache Summary¶
If you’re using spack within a development team, consider setting up source mirrors with binary caches. Source mirrors will let you replicate a spack environment on a machine without external internet access, and binary mirrors free you from the burden of recompiling everything from scratch and save you development time.
