ecscope

ecscope lets you monitor AWS ECS resources from the terminal.

It does so by offering a TUI which shows services, tasks and containers in a single view. Instead of having to log into several accounts (or change regions) via the AWS website, you're able to view relevant information for ECS deployments in one place. You can group services by configuring them via a "profile", and have ecscope load it up. Besides the TUI, ecscope can also show deployments updates via a minimal web interface.

💾 Installation

homebrew:

brew install dhth/tap/ecscope

cargo:

cargo install ecscope

Or get the binaries directly from a Github release. Read more about verifying the authenticity of released artifacts here.

📃 Profiles

Adding a profile

The first thing you'll do after installing ecscope is to set up a profile. A profile is simply configuration that groups together ECS resources you want to monitor in one go. You set up a profile using:

ecscope profiles add <PROFILE>

This will generate a TOML file in your config directory that looks like this:

[[clusters]]
keys = ["<KEY>"]
arn = "arn:aws:ecs:eu-central-1:<ACCOUNT_ID>:cluster/<CLUSTER_NAME>"
services = [
  "service-a",
  "service-b"
]
# use this to provide configuration and credentials via environment variables
# https://docs.aws.amazon.com/sdkref/latest/guide/environment-variables.html
config_source = "env"

[[clusters]]
keys = ["<KEY>"]
arn = "arn:aws:ecs:eu-central-1:<ACCOUNT_ID>:cluster/<CLUSTER_NAME>"
services = [
  "service-a",
  "service-b"
]
# use this to leverage a profile contained in the shared AWS config and credentials files
# https://docs.aws.amazon.com/sdkref/latest/guide/file-format.html
config_source = "profile:<PROFILE_NAME>"

[[clusters]]
keys = ["<KEY>"]
arn = "arn:aws:ecs:eu-central-1:<ACCOUNT_ID>:cluster/<CLUSTER_NAME>"
services = [
  "service-a",
  "service-b"
]
# use this when you want to provide configuration and credentials via environment variables
# but want to assume another role for performing the actual operations
config_source = "assume:<IAM_ROLE_ARN>"

Listing profiles

You can list configured profiles using ecscope profiles list.

🛠 AWS Configuration

ecscope supports getting AWS configuration from the following sources:

Environment variables

This is configured by setting config_source to "env" in the profile config. The following environment variables need to be set for this option.

AWS_ACCESS_KEY_ID
AWS_SECRET_ACCESS_KEY
AWS_SESSION_TOKEN
AWS_REGION

Shared config

Use this option when you want to leverage profiles set in the shared AWS config for authentication and configuration.

ecscope can be configured to use this option by setting config_source to "profile:<PROFILE>" in the profile config.

⏳ Deployments

ECS deployments can be viewed using the deps command.

$ ecscope deps -h

Usage: ecscope deps [OPTIONS] <PROFILE>

Arguments:
  <PROFILE>  Profile to use

Options:
  -s, --service-filter <REGEX>  Filtration query for service names
  -k, --key-filter <REGEX>      Filtration query for cluster keys
  -S, --state <STRING>          Deployment state to query for [possible values: finished, in-progress, failing]
  -c, --config-dir <PATH>       Config directory (to override ecscope's default config directory)
  -f, --format <STRING>         Format to use [default: json] [possible values: delimited, json, plain]
      --debug                   Output debug information without doing anything
  -m, --mode <STRING>           Output mode [default: default] [possible values: default, web]
      --web-skip-opening        Whether to skip opening web results in browser (when --mode=web)
  -h, --help                    Print help (see more with '--help')

ecscope deps <PROFILE>

# filter by cluster keys
ecscope deps <PROFILE> -k prod

# filter by cluster keys
ecscope deps <PROFILE> -k '(qa|prod)'

# filter by service names
ecscope deps <PROFILE> -s '.*-service'

# only show deployments that are finished
ecscope deps <PROFILE> --state finished

# only show deployments that are pending
ecscope deps <PROFILE> --state pending

# only show deployments that are failing
ecscope deps <PROFILE> --state failing

By default, the deps command outputs results in the JSON format.

Sample output

ecscope deps <PROFILE> -s auth

[
  {
    "service_name": "authentication-service",
    "keys": "qa",
    "cluster_arn": "arn:aws:ecs:eu-central-1:<REDACTED>:cluster/authentication-service-infrastructure-qa",
    "deployment_id": "ecs-svc/<REDACTED>",
    "status": "PRIMARY",
    "running_count": 3,
    "desired_count": 3,
    "pending_count": 0,
    "failed_count": 0
  },
  {
    "service_name": "authentication-service",
    "keys": "staging",
    "cluster_arn": "arn:aws:ecs:eu-central-1:<REDACTED>:cluster/authentication-service-infrastructure-staging",
    "deployment_id": "ecs-svc/<REDACTED>",
    "status": "PRIMARY",
    "running_count": 1,
    "desired_count": 1,
    "pending_count": 0,
    "failed_count": 0
  },
  {
    "service_name": "authentication-service",
    "keys": "prod",
    "cluster_arn": "arn:aws:ecs:eu-central-1:<REDACTED>:cluster/authentication-service-infrastructure-prod",
    "deployment_id": "ecs-svc/<REDACTED>",
    "status": "PRIMARY",
    "running_count": 3,
    "desired_count": 3,
    "pending_count": 0,
    "failed_count": 0
  }
]

Tabular Output

You can view the output of deps command as a table as follows (uses tbll):

ecscope deps <PROFILE> -s auth -f delimited |
    (read -r header && echo "$header" && sort) |
    tbll -C 2,3

┌────────────────────────┬─────────┬─────────┬───────────────┬───────────────┬───────────────┬──────────────┐
│ service_name           │ keys    │ status  │ running_count │ desired_count │ pending_count │ failed_count │
├────────────────────────┼─────────┼─────────┼───────────────┼───────────────┼───────────────┼──────────────┤
│ authentication-service │ prod    │ PRIMARY │ 3             │ 3             │ 0             │ 0            │
│ authentication-service │ qa      │ PRIMARY │ 3             │ 3             │ 0             │ 0            │

└────────────────────────┴─────────┴─────────┴───────────────┴───────────────┴───────────────┴──────────────┘

Web UI

Deployments can also be viewed through a web UI (using --mode web). This allows you to monitor deployment status in real time with a simple interface.

📟 Monitoring TUI

Once a profile is configured, you can begin monitoring ECS deployments via ecscope's TUI.

$ ecscope monitor -h

Usage: ecscope monitor [OPTIONS] <PROFILE>

Arguments:
  <PROFILE>  Profile to use

Options:
  -s, --service-filter <REGEX>  Filtration query for service names
  -k, --key-filter <REGEX>      Filtration query for cluster keys
      --debug                   Output debug information without doing anything
  -h, --help                    Print help

The TUI displays running tasks for each configured service, along with their respective containers. Additionally, details for the currently selected service, task, and container are shown in dedicated panes to the right.

The TUI also supports refreshing of results — either on a schedule or manually. Additionally, you can mark specific services to be targeted for the refresh.

Services List
    m                    mark service for auto refresh

Filtering services to be monitored

You can filter services using two kinds of filter queries, one for the cluster key and the other for the service name.

# will show all services that match a regex .*-service
ecscope monitor profile -s '.*-service'
# will show all services in clusters where a key matches the regex qa|staging
ecscope monitor profile -k 'qa|staging'
# combine both filters
ecscope monitor profile -s '.*-service' -k 'qa'

🔐 Verifying release artifacts

In case you get the ecscope binary directly from a release, you may want to verify its authenticity. Checksums are applied to all released artifacts, and the resulting checksum file is attested using Github Attestations.

Steps to verify (replace A.B.C in the commands below with the version you want):

Download the sha256 checksum file for your platform from the release:

curl -sSLO https://github.com/dhth/ecscope/releases/download/vA.B.C/ecscope-x86_64-unknown-linux-gnu.tar.xz.sha256

Verify the integrity of the checksum file using gh.

gh attestation verify ecscope-x86_64-unknown-linux-gnu.tar.xz.sha256 --repo dhth/ecscope

Download the compressed archive you want, and validate its checksum:

curl -sSLO https://github.com/dhth/ecscope/releases/download/vA.B.C/ecscope-x86_64-unknown-linux-gnu.tar.xz
sha256sum --ignore-missing -c ecscope-x86_64-unknown-linux-gnu.tar.xz.sha256

If checksum validation goes through, uncompress the archive:

tar -xzf ecscope-x86_64-unknown-linux-gnu.tar.xz
cd ecscope-x86_64-unknown-linux-gnu
./ecscope
# profit!
