### Cluster-wide PCAP
Generate a cluster-wide PCAP file from any point in time. Filter by time range, specific nodes, and BPF expressions (e.g. `net`, `ip`, `port`, `host`) to capture exactly the traffic you need — across the entire cluster, in a single file. Download and analyze with Wireshark, tshark, or any PCAP-compatible tool — or let your AI agent download and analyze programmatically via MCP.
Store snapshots locally or in S3/Azure Blob for long-term retention.

### Example: IRSA (recommended for EKS)
[IAM Roles for Service Accounts (IRSA)](https://docs.aws.amazon.com/eks/latest/userguide/iam-roles-for-service-accounts.html) lets EKS pods assume an IAM role without static credentials. EKS injects a short-lived token into the pod automatically.
**Prerequisites:**
1. Your EKS cluster must have an [OIDC provider](https://docs.aws.amazon.com/eks/latest/userguide/enable-iam-roles-for-service-accounts.html) associated with it.
2. An IAM role with a trust policy that allows the Kubeshark service account to assume it.
**Step 1 — Create an IAM policy scoped to your bucket:**
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"s3:GetObject",
"s3:PutObject",
"s3:DeleteObject",
"s3:GetObjectVersion",
"s3:DeleteObjectVersion",
"s3:ListBucket",
"s3:ListBucketVersions",
"s3:GetBucketLocation",
"s3:GetBucketVersioning"
],
"Resource": [
"arn:aws:s3:::my-kubeshark-snapshots",
"arn:aws:s3:::my-kubeshark-snapshots/*"
]
}
]
}
```
> For read-only access, remove `s3:PutObject`, `s3:DeleteObject`, and `s3:DeleteObjectVersion`.
**Step 2 — Create an IAM role with IRSA trust policy:**
```bash
# Get your cluster's OIDC provider URL
OIDC_PROVIDER=$(aws eks describe-cluster --name CLUSTER_NAME \
--query "cluster.identity.oidc.issuer" --output text | sed 's|https://||')
# Create a trust policy
# The default K8s SA name is "<release-name>-service-account" (e.g. "kubeshark-service-account")
cat > trust-policy.json <<EOF
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": {
"Federated": "arn:aws:iam::ACCOUNT_ID:oidc-provider/${OIDC_PROVIDER}"
},
"Action": "sts:AssumeRoleWithWebIdentity",
"Condition": {
"StringEquals": {
"${OIDC_PROVIDER}:sub": "system:serviceaccount:NAMESPACE:kubeshark-service-account",
"${OIDC_PROVIDER}:aud": "sts.amazonaws.com"
}
}
}
]
}

Or via `--set`:

--set tap.snapshots.cloud.s3.bucket=my-kubeshark-snapshots \
--set tap.snapshots.cloud.s3.region=us-east-1 \
--set tap.annotations."eks\.amazonaws\.com/role-arn"=arn:aws:iam::ACCOUNT_ID:role/KubesharkS3Role
```
No `accessKey`/`secretKey` is needed — EKS injects credentials automatically via the IRSA token.
The hub pod's service account must be annotated for IRSA with an IAM role that has S3 access to the bucket.
