# Upgrading to 1.8.13
|
|
|
|
## Introduction
|
|
|
|
This guide explains how to best upgrade a multi-datacenter Consul deployment that is using
|
|
a version of Consul >= 1.6.9 and < 1.8.13 while maintaining replication. If you are on a version
|
|
older than 1.6.9, please follow the link for the version you are on from [here](/docs/upgrading/instructions).
|
|
|
|
In this guide, we will be using an example with two datacenters (DCs) and will be
|
|
referring to them as DC1 and DC2. DC1 will be the primary datacenter.
|
|
|
|
## Requirements
|
|
|
|
- All Consul servers should be on a version of Consul >= 1.6.9 and < 1.8.13.
|
|
|
|
## Assumptions
|
|
|
|
This guides makes the following assumptions:
|
|
|
|
- You have at least two datacenters configured and have ACL replication enabled. If you are
|
|
not using multiple datacenters, you can follow along and simply skip the instructions related
|
|
to replication.
|
|
|
|
## Considerations
|
|
|
|
There are not too many major changes that might cause issues upgrading from 1.6.9, but notable changes
|
|
are called out in our [Specific Version Details](/docs/upgrading/upgrade-specific#consul-1-8-0)
|
|
page. You can find more granular details in the full [changelog](https://github.com/hashicorp/consul/blob/main/CHANGELOG.md#183-august-12-2020).
|
|
Looking through these changes prior to upgrading is highly recommended.
|
|
|
|
## Procedure
|
|
|
|
**1.** Check replication status in DC1 by issuing the following curl command from a
|
|
consul server in that DC:
|
|
|
|
```shell-session
|
|
$ curl --silent --header "X-Consul-Token: $MASTER_TOKEN" "localhost:8500/v1/acl/replication?pretty"
|
|
```
|
|
|
|
You should receive output similar to this:
|
|
|
|
```json
|
|
{
|
|
"Enabled": false,
|
|
"Running": false,
|
|
"SourceDatacenter": "",
|
|
"ReplicationType": "",
|
|
"ReplicatedIndex": 0,
|
|
"ReplicatedRoleIndex": 0,
|
|
"ReplicatedTokenIndex": 0,
|
|
"LastSuccess": "0001-01-01T00:00:00Z",
|
|
"LastError": "0001-01-01T00:00:00Z"
|
|
}
|
|
```
|
|
|
|
-> The primary datacenter (indicated by `primary_datacenter`) will always show as having replication
|
|
disabled, so this is normal even if replication is happening.
|
|
|
|
**2.** Check replication status in DC2 by issuing the following curl command from a
|
|
consul server in that DC:
|
|
|
|
```shell-session
|
|
$ curl --silent --header "X-Consul-Token: $MASTER_TOKEN" "localhost:8500/v1/acl/replication?pretty"
|
|
```
|
|
|
|
You should receive output similar to this:
|
|
|
|
```json
|
|
{
|
|
"Enabled": true,
|
|
"Running": true,
|
|
"SourceDatacenter": "dc1",
|
|
"ReplicationType": "tokens",
|
|
"ReplicatedIndex": 672,
|
|
"ReplicatedRoleIndex": 1,
|
|
"ReplicatedTokenIndex": 677,
|
|
"LastSuccess": "2020-09-14T17:06:07Z",
|
|
"LastError": "2020-09-14T16:53:22Z"
|
|
}
|
|
```
|
|
|
|
**3.** Upgrade the Consul agents in all DCs to version 1.8.13 by following our [General Upgrade Process](/docs/upgrading/instructions/general-process).
|
|
|
|
**4.** Confirm that replication is still working in DC2 by issuing the following curl command from a
|
|
consul server in that DC:
|
|
|
|
```shell-session
|
|
$ curl --silent --header "X-Consul-Token: $MASTER_TOKEN" "localhost:8500/v1/acl/replication?pretty"
|
|
```
|
|
|
|
You should receive output similar to this:
|
|
|
|
```json
|
|
{
|
|
"Enabled": true,
|
|
"Running": true,
|
|
"SourceDatacenter": "dc1",
|
|
"ReplicationType": "tokens",
|
|
"ReplicatedIndex": 672,
|
|
"ReplicatedRoleIndex": 1,
|
|
"ReplicatedTokenIndex": 677,
|
|
"LastSuccess": "2020-09-14T17:15:16Z",
|
|
"LastError": "0001-01-01T00:00:00Z"
|
|
}
|
|
```
|
|
