Find your Synology model, DSM version and CPU architecture
Read the model, DSM build and local IP address in Info Center, then match the exact NAS to the CPU architecture required by a container image.

When an app guide asks whether your Synology can run an image, write down three separate facts: the exact NAS model, its installed DSM version and the CPU architecture. An app image and a DSM package can have different compatibility requirements.
Read the model and version in DSM
- Sign in to the NAS and open Control Panel → Info Center → General.
- Record the full model name, including any suffix such as
+, and the DSM version and build shown on that NAS. - If you are checking a package, also open Package Center and record the installed package version or check what it offers for your NAS.
If DSM does not open, try locating the NAS on your network. Synology Web Assistant can show Version and Model name for discovered devices. If it finds several units, confirm which one belongs to you before using the displayed information. An unexpected Not installed status on a NAS with existing data calls for diagnosis before proceeding.
Synology Web Assistant example. Huncode cropped the original and underlined the Version and Model name columns. The example values belong to the devices shown.
Read the NAS address for a local app
Open Info Center → Network and read the IP address for the connection used on your home network. If several interfaces appear, compare the address with the one you use to open DSM or ask the NAS administrator. A container's published port comes from its installation recipe. Use that port with the NAS address when opening the app from another device on the same network.
Check the CPU architecture and package separately
Look up the full model in Synology Knowledge Center’s What kind of CPU does my Synology storage system have? table. Use its CPU Arch column when comparing processor architectures. The Package Arch column describes a Synology package platform. If you already have an authorized shell on the NAS, run uname -m to read the kernel architecture without changing settings. If you need a temporary session, use the DSM SSH maintenance guide.
| Image publisher's label | What to look for |
|---|---|
amd64, x86_64 | 64-bit x86 support. |
arm64, aarch64, arm64v8 | 64-bit ARM support. |
arm/v7, arm32v7 | 32-bit ARMv7 support. Check that the exact image tag includes this variant. |
Check the architectures listed for the exact image tag and each required service in the app stack. Then check Container Manager availability for your model and DSM version. If an image pull reports no matching manifest, compare the tag and architecture again before trying a different image.
