Setup `metal-01` under `logos.test` for the LEZ testnet v2

[Arjentix]

Need to setup metal-01.he-eu-hel1.misc.lez.status.im stage as a LEZ testnet v2. It should be located under logos.test.

Details

• Currently this stage setup is located in infra-misc and there we have just standalone LEZ Sequencer. This is no longer needed and can be removed, but this old setup and https://github.com/status-im/infra-misc/pull/474) could be used as inspiration for a new setup.
• Need to move it to logos.test but don't change testnet.lez.logos domain name to it until we explicitly ask for it
• Here it's needed to setup 4 things (with pinned versions):
  • Logos Blockchain Node v0.13-rc2
  • LEZ Sequencer v0.2.0-rc5
  • LEZ Indexer v0.2.0-rc5
  • LEZ Explorer v0.2.0-rc5
• Versions of each of these services should be pinned as described above

Services are connected as follows:

graph TD;
    S[LEZ Sequencer] --> N[Logos Blockchain Node];
    I[LEZ Indexer] --> N[Logos Blockchain Node];
    E[LEZ Explorer] --> I[LEZ Indexer];

Loading

How to test

• No ERROR logs from services (at least from LEZ)
• LEZ Sequencer reports about produced blocks
• Opening LEZ Explorer page first reports that no blocks found, and after some time (I'd say 1 hour) starts showing blocks. No RPC Error messages

Deadline

Deadline is 30 June. After that if everything will be stable we'll ask to change testnet dns to this stage.

I'll attach configs I used for manual deployment in the comment section.

I have renamed:

• metal-01.he-eu-hel1.misc.lez to lez-01.he-eu-hel1.logos.dev
• metal-02.he-eu-hel1.misc.lez to devnet-01.he-eu-hel1.misc.lez-legacy

Changes:

• infra-misc#c9d79e2a - lez: move metal-01 host to infra-logos
• lez: add lez-01 Hetzner host #30

[jakubgs]

Managed to build blockchain Docker image for 0.1.3-rc.12 release using repo Dockerfile:

 > docker build --build-arg LB_NODE_VERSION=0.1.3-rc.12 -t harbor.status.im/logos-blockchain/logos-blockchain:0.1.3-rc.12 .
...
 > docker run --rm -it --entrypoint=/usr/local/bin/logos-blockchain-node harbor.status.im/logos-blockchain/logos-blockchain:0.1.3-rc.12 --help

 > echo $?
132

But it exits with 132 code, which might suggest an issue with my old CPU.

[jakubgs]

Works on lez-01.he-eu-hel1.logos.dev, so it was the missing CPU features:

jakubgs@lez-01.he-eu-hel1.logos.dev:~ % d run --rm -it harbor.status.im/logos-blockchain/logos-blockchain:0.1.3-rc.12 --version
logos-blockchain-node 0.1.3-rc.12
commit:  2de2822 (tag 0.1.3-rc.12)
target:  x86_64-unknown-linux-gnu
profile: release
rustc:   rustc 1.96.0 (ac68faa20 2026-05-25)

[jakubgs]

Whoops, incorrectly put the host under logos.dev, fixed:

• lez: move from dev to test fleet #32

[jakubgs]

I have an initial roles setup mostly ready in this PR:

• logos-execution-zone: initial role setup #33

Will finish deployment tomorrow.

[jakubgs]

I have the containers running:

CONTAINER ID   NAMES                       IMAGE                                                                                 CREATED         STATUS

But Indexer logs are full of this:

And Sequencer logs are full of this:
