How to upgrade canister by canister_id and wasm file

Developers Getting Started

i want to upgrade the canister created by code, dfx deploy is not working, any way to resolve it?

2

Any answers ? :thinking: :thinking: :thinking:

Got the same question. I tried following but hit the error Cannot find canister <canister_id>

dfx canister --network ic --no-wallet install <canister_id> --all --mode reinstall

still uses the rust agent which dfx uses but it works last time I check:

use ic_agent::{
    Agent, 
    ic_types::Principal, 
    identity::{Identity, BasicIdentity},
    agent::http_transport::ReqwestHttpReplicaV2Transport
};
use ic_utils::interfaces::ManagementCanister;
use ic_utils::interfaces::management_canister::builders::InstallMode;
use ic_utils::call::AsyncCall;
use ring::signature::Ed25519KeyPair;
use candid::{Encode,Decode,CandidType,};
use std::{time::Duration};
use std::{
    fs::File,
};
use std::io::Read;
use garcon::Delay;
use tokio::runtime::Runtime;


fn waiter_with_timeout(duration: Duration) -> Delay {
    Delay::builder().timeout(duration).build()
}
fn expiry_duration() -> Duration {
    // 5 minutes is max ingress timeout
    Duration::from_secs(60 * 5)
}

async fn put_code_on_the_canister(can_id: &Principal, agent: &Agent, filename: &str, mode: InstallMode, canister_init_raw_put_bytes: Vec<u8>) {
    let mut f = File::open(filename).unwrap();
    let mut wasmmodbytes: Vec<u8> = Vec::<u8>::new();
    println!("wasm_bytes_len: {:?}", f.read_to_end(&mut wasmmodbytes).unwrap() );
    let management = ManagementCanister::create(&agent);
    println!("{:?}",
        management.install_code(can_id, wasmmodbytes.as_slice())
            .with_mode(mode)
            .with_raw_arg(canister_init_raw_put_bytes) 
            .call_and_wait(waiter_with_timeout(expiry_duration()))
            .await.unwrap()
    );
}

fn main() {
    let can_id = Principal::from_text("the-canister-principal").unwrap();

    let sk: [u8; 32] = [put 32 bytes here];
    let pub_key: [u8; 32] = [put 32 bytes here];
    let caller: BasicIdentity = BasicIdentity::from_key_pair(
        Ed25519KeyPair::from_seed_and_public_key(
            &sk,
            &pub_key

    let agent: Agent = Agent::builder()
        .with_transport(ReqwestHttpReplicaV2Transport::create("https://ic0.app").unwrap())

    let rt = Runtime::new().unwrap();
    rt.block_on(async {

    });

Thanks a lot for the share! Ultimately I definitely have to automate the task in any case, therefore your script is really interesting

Thanks for your answer, but how to got the “sk” and “pub_key” from my identity? I‘m not familiar with rust and motoko.
