+== Getting fonts to work in containers ==
+When building a container using {{Nixpkgs Manual|name=dockerTools.streamLayeredImage|anchor=#ssec-pkgs-dockerTools-streamLayeredImage}} or {{Nixpkgs Manual|name=dockerTools.buildLayeredImage|anchor=#ssec-pkgs-dockerTools-buildLayeredImage}}, the image won't include any fonts, and so Chrome won't be able to render any text. To handle this, you must add {{nixos:package|fontconfig}} to the image, along with the fonts you want included.
+Adding fonts to your image will only add them at {{ic|/share/fonts}}, but fontconfig expects them at {{ic|/usr/share/fonts}}, so you just link the fonts to that directory:
+<syntaxhighlight lang="nix">
+{
+  dockerTools,
+  chromium,
+  fontconfig,
+  maple-mono,
+  bashNonInteractive,
+  ...
+}:
+dockerTools.streamLayeredImage {
+  name = "chromium";
+  tag = "latest";
+  contents = [
+    chromium
+    fontconfig.out # The default .bin output only contains binaries
+    # Fontconfig already contains a minimal set of DejaVu fonts, adding extra
+    # fonts is optional
+    maple-mono.NF
+  ];
+  # This part is only necessary if you're adding extra fonts
+  fakeRootCommands = ''
+    #!${bashNonInteractive}
+    mkdir -p usr/share
+    ln -s /share/fonts usr/share/fonts
+  '';
+}
+</syntaxhighlight>
+Chrome will then be able to discover the DejaVu and Maple Mono NF fonts through fontconfig.
+If you instead want to use fonts from the {{nixos:package|texlivePackages}} package set, you'll need to symlink the {{ic|/fonts}} directory instead of {{ic|/share/fonts}} as the texlive packages have a different structure:
+<syntaxhighlight lang="nix">
+{
+  dockerTools,
+  chromium,
+  fontconfig,
+  texlivePackages,
+  bashNonInteractive,
+  ...
+}:
+dockerTools.streamLayeredImage {
+  name = "chromium";
+  tag = "latest";
+  contents = [
+    chromium
+    fontconfig.out
+    texlivePackages.opensans
+  ];
+  fakeRootCommands = ''
+    #!${bashNonInteractive}
+    mkdir -p usr/share
+    ln -s /fonts usr/share/fonts
+  '';
+}
