Possible to restart a specific deployment via API?
Hi there,
Is it possible to restart a specific deployment with an API call?
This is to save memory and CPU and free those up when there is no volume of requests.

N/Adoes the cron template not fit your usecase for this?
It does, but it sometimes restarts even when there is an ongoing job, and that job is impacted
want to restart when there is no ongoing job.
gotcha, do you know golang?
not right now, but i think i might be familiar
it's simple syntax, read the source code of the cron template, it's golang
ah okay, is there a repo where i can find this
GitHub

const serviceInstanceRedeployMutation =
mutation serviceInstanceRedeploy($environmentId: String!, $serviceId: String!) {
serviceInstanceRedeploy(environmentId: $environmentId, serviceId: $serviceId)
}
;
const getLatestDeploymentQuery =
query Deployments($first: Int, $input: DeploymentListInput!) {
deployments(input: $input, first: $first) {
edges {
node {
id
status
}
}
}
}
;
could you please confirm if i'm running this correctly?
i've noticed i can only restart the service once
while i do get a 200, the services not really restart, is this something to do with deployment id?
async function redeployService(serviceId: string): Promise<{ serviceId: string; status: string; error?: string }> {
if (!RAILWAY_API_ENDPOINT) {
throw new Error('RAILWAY_BACKEND_URL is not defined in the environment variables');
}
try {
const latestDeploymentId = await getLatestDeploymentID(serviceId);
const response = await fetch(RAILWAY_API_ENDPOINT, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': Bearer ${process.env.RAILWAY_API_TOKEN},
},
body: JSON.stringify({
query: serviceInstanceRedeployMutation,
variables: {
environmentId: process.env.RAILWAY_ENVIRONMENT_ID,
serviceId: serviceId,
deploymentId: latestDeploymentId,
},
}),
});
if (!response.ok) {
const errorText = await response.text();
throw new Error(HTTP error! status: ${response.status}, body: ${errorText});
}
const data = await response.json();
if (data.errors) {
throw new Error(JSON.stringify(data.errors));
}
return { serviceId, status: 'redeployed' };
} catch (error: any) {
console.error(Error redeploying service ${serviceId}:, error);
return { serviceId, status: 'failed', error: error.message };
}
}you want to restart the service, not redeploy it
i can confirm i'm using correct details in the backend
ah okay, so this one?
mutation deploymentRestart($id: String!) {
deploymentRestart(id: $id)
}
yep
sigh, thanks man, i'll try with this
sounds good
maybe at some point it will be worth it to invest some time into your code so you dont have to keep restarting it to save memory?
